You mean for like a dispenser?\nComercial electric cream dispensers use a hose that comes integrated with the bag that the cream comes in.  You put this hose inside a wheel mechanisms that has bumps on it, as the wheel spinks slowly the bumps squeeze the rubber hose for a short length of the hose, and thus pumps cream out.  This can be applied to milk too.

his applies only to transfer pumps since we deliberate add a gas load to the chamber and measure the quantity of gas issuing from the mechanical pump's exhaust. The method works as long as the gas chosen is not condensable, not captured in the foreline trap, does not dissolve in oil and is present in sufficient quantity to be measured.\n\nIf the mechanical pump has gas ballast, make sure it is off. Note the chamber's steady state pressure under the gas load. Put a bubble flow meter on the pump's exhaust, and measure the flow rate in cc per sec at atmospheric pressure. Using the gas in = gas out (at constant chamber pressure) principle, the gas entering must equal the measured throughput. If more precise numbers are needed, measure the exhaust gas temperature and the barometric pressure and re-calculate the quantity of gas at STP with Boyle's and Charles' law combined:\n\n(P1 x V1) / T1 = (P2 x V2) / T2\n\nExample The measured flow of gas at the pump's exhaust is 2.3 atm cc per minute from a chamber at a measured pressure of 1.4 x 10-5 torr. The exhaust gas temperature is 32°C and the barometric pressure is 750 mm Hg. What is the (corrected) effective pumping speed from the chamber?\n\n2.3 atm cc per min = (2.3/60) atm cc per sec\n= (2.3/60) x (760/1000) torr.liter per sec\n= (2.3/60)x (760/1000) torr.liter per sec at 750 torr and 32 °C\n= (2.3/60) x (760/1000) x (750/760) x (273/305) torr.liter per sec at STP\n= 0.0257 torr.liter per sec\nEffective pumping speed\n= (0.0257/1.4x10-5) liter per sec\n= 1838 liter per sec

If you want to measure the volume of sound, it is measured in decibles.\n\nIf you want to measeure the width or band or sound it is measured in Hertz or mega hertz. For this you need an oscilla scope.

Measure concentration. Use a dummy (with water only) measuring that with a LabPro probe. Then compare that to a certain volume of a variable soft drink. I did this in high school, hope it works!

acidity test\nThis test measures the lactic acid in the milk. If the acidity is higher than 0.19%, then the milk quality is poor and cannot be processed. If the acidity is lower than normal (e.g. 0.10% lactic acid) then the milk is of poor bacterial quality or sodium hydroxide/bicarbonate might have been added. For this test you will need a white porcelain dish, a 10 ml pipette, a 1 ml pipette, a burette (0.1 ml graduations), a glass rod for stirring, a phenophtalein indicator solution (0.5% in 50% alcohol) and a 0.1 N Sodium hydroxide solution. Measure 9 ml of the milk into the dish, add 1 ml of phenophtalein and from the burette, slowly add the 0.1 N sodium hydroxide solution while mixing continuously, until a faint pink colour appears. The more Sodium Hydroxide you have to add before it turns pink, the more acid the milk.

Rheometer measures samples above boiling point. \n\nThe Sealed Cell measures viscoelastic rheological properties of solutions without loss of volatile components. Enabling measurements under pressure with full dynamic oscillation and viscometric capability, system has frictionless air-bearing seal that permits dynamic oscillatory testing throughout frequency range of rheometer. Product can also test pastes and semisolid materials at elevated pressures and temperatures utilizing parallel plate measuring system.

Oops! Wrong answer.\n\nWhat I should have done first is check the density of both liquids before answering.\n\nWhole milk has a density of 1030 km/m3,\nwhile water at 20 degrees C is 998.21 km/m3.\n\nIf they have the same volume, than whole milk is a little heavier than water. Which isn't surprising, since milk is about 87% water.

This is an 'empirical question'.  That means you can perform a test (experiment) to determine the answer.  Do the test.  Weigh yourself. Take a one hour bath.  Dry off.  Weigh yourself again.  Be sure not to get your hair wet because you can't dry that off quickly.\n\nLimitations may include the accuracy and reproducibility of your scale and its ability to measure very small changes.\n\nTry it!\nGood luck.

You know three of the four things needed. Try C1V1=C2V2, or an equality.\n\n                          m/ml=m/x

Milk Analysis....   \n 1)Human breast milk is thin and high in lactose, its primary sugar. Human milk contains, on average 1.1% protein, 4.2% fat, 7.0% lactose (carbohydrate) and supplies 72 kcal of energy per 100 grams.\n    2) Cow's milk is higher in protein and lower in carbohydrate than human milk. It is composed of about 3.3 to 3.5% protein, 3.5 to 3.7% milkfat, and 4.6% lactose and supplies 66 kcal of energy per 100 grams, or about 634 Calories (2650kJ) per litre. It contains 12.6% milk solids and about 88% water. Its main protein is casein 80%), while whey proteins make up most of the rest.\n    3)Vitamin C, folic acid, sodium, iron and calcium levels also differ significantly.

Try Global Spec. It's free and allows you to put in your desired torque and rpm, then shows you matching products. Keep in mind they will spam the email account you register with mercilessly.

Well, if you want to measure their growth in milk you need:\n\nPure culture of the bacteria in question, sterile milk, sterile glass tubes and a spectrophotometer.  This will measure the density of the bacteria in liquid culture.  I don't know what equipment you have access too (pipetts, tubes, a spectrophotometer etc).\n\nIf you've isolated the bacteria from milk and want to just measure their growth in "whatever", you can use any sterile growth medium that supports the growth of the isolated bacteria.  Again, measuring growth is most easily accomplished by use of a spectrophotometer.  \n\nGrowing bacteria on a plate to decide which grows faster is fairly insane, unless they have significant differences in growth.  I mean, are you going to stare at an agar plate for 24 hours just to see that at 14 hours 5 minutes a tiny pinpoint on plate A was visible, but it took 15 hours and 22 minutes for a colony of the same size on plate B?  No, of course you're not, it's not even plausible.\n\nWith liquid culture, you can take readings every hour for 8 hours and at 24 hours or something.\n\nYou can also dilute and spread-plate the bacteria from liquid cultures onto agar plates if you have your heart set on using them and achieving an exact count for bacterial populations.  But use of a spec still allows for comparisons between species, even without an exact population number.

There is indeed a machine, called a light meter, that you can use. You an also use a device called a Secchi disk which is much more low tech.

The low technology approach is to use a densitometer.  This can be as simple as a hydrometer as used in the brewing industry to check for specific gravity (density).  From a measured density and a known volume and if you know the densities of both liquid components of a binary mixture you can work out the relative proportions of each using simultaneous equations and hence the concentration of one in the other.

I agree; c) is the right choice.  The other units are used to measure:\n\na)  power ratio\nb)  pressure\nd)  pressure (again)

ml measurement are associated with liquid materials like perfume, sodas, lotions, etc. hope i was able answer the question.

This is Measured in MTBF or Mean Time Before Failiure. Noramlly if you know the manufacturer you can get information on that through thier website.
