What is the maximum allowable time to prime a 1500 GPM pump on a fire engine?
99895
45 seconds on pumpers greater than 1250 gpm otherwise its 30 seconds on 1250 or less
683205
About 1000 feet per sec.

I have put a T3/T4 Hybrid on a 99 GS and to be honest, it's not smart to do unless your doing your fuel system and pistons. You would get 6psi max without blowing anything up so you would be basically be doing it for the sound of the air being vented to the atomsphere. If your gonna go turbo, your better off gettin a turbo motor (4G63T) and building from there. Good Luck Bro

Use silicone,just make sure it is clean and dry,and then wait at least twenty four hours before putting gasoline in the tank.It worked for me,except it wasn't a Nissan Maxima.

Depends on your application.\n\nPump water from a shallow (less than 20ft)or deep (greater than 20ft) well?\nHow much volume(gpm) and pressure(psi) are you looking for?\nBased on standard house current at 110VAC or off of a car battery(12V) and how long do you plan to have this pump running (few minutes at a time or hr's or day's on end)?\n\nYour question can be simple or a major under taking. \n\nA simple pump, using an old washmachine pump and motor you can come up with a basic pump. This will work on a shallow application, meaning the pump can't draw water from a resavoir being very deep, maybe a few feet. \nA sump pump is also a very shallow well type, works from a jet principle, but can't deliver a lot of pressure 10-15psi for a short period of time.\n\nWater wells which are deep, > 30ft, usually have the pump submerged into the water which then pushes the water out vs drawing the water up.\nSome of the older pumps were of a piston design, inefficient compared todays jet pump standards.\n\nOtherwise an electric moter and a mechanical pump.

on average about 5 to 6 sec per 10 units at least that is what i have found to work the best. otherwise the best thing to do is just trial and error!

It all depends on physics and how you drain the pool.\n\nOn average, it can take several hours with pumps

Where are you getting your fuel pumps from?... I have a friend who is a mechanic and he said most auto parts stores sell junk fuel pumps (for GM atleast)....You'll put 10 in before you actually get a good one....\n\nNow if you want to spend a couple extra bucks, go to the GM dealer and buy one from them.... Thats what I did with my truck and it wasen't that much more...\n\nOr ask your auto parts stores, if they sell AC Delco pumps...\n\nGood Luck

Depending of the flow rate and the definition of "high head" it could be a multistage centrifugal or a positive displacement pump. \n\nIf given only one choice then a positive displacement pump would be the likely choice but not necessarily the best choice. \n\nFor example: to pump 10 gallons a minute up to 1500 psig, a positive plunger pump would be the likely choice. However, to pump 1000 gpm up to 1000 psig, a multistage centrifugal would probably be the best choice.\n\nMore information is needed to make a good recommendation.

As far as i know it should be around 10 degrees BTDC (before top dead center) Chrysler Big Block engines are 10 degrees BTDC so i would think small blocks are also.

all you want, just a little at a time. Try a concrete boom pump if you want any kind of volumne. A Putzmister, 52 meter can pump 200+ cu yards an hour.

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

It depends on the size and type.\n\nhttp://www.hanford.gov/fire/safety/extingrs.htm

One which is not interrupted. This can be done with a reserve tank, for example, as in an "air hose". It can deliver a constant supply of air, from the reserve and then ,as the pressure begins to dissipate, the pump comes back on, keeping the supply constant. The pressure in the tank is maintained at a higher level than at the "regulated" out put.

The maximum possible coefficient of performance, B, can only happen in an ideal heat pump, or the Carnot heat pump. The formula for coefficient of performance is:\n\nB=Tl/(Th-Tl) where Tl is the low temperature and Th is the high temperature, both in kelvin.\n\nB= 266 K/(295 K - 266 K)\nB=9.17 is the maximum possible coefficient of performance.

probably between 16- 23 per hour

Trey is correct, however I just ran into some red tape with two 20,000 gallon diesels in southern KY. My customer was really pushing to get these things out of the ground.. Fast! As it ends up, several states have a set time frame on how long a (ust) underground storage tank can sit empty. Your state fire marshel would be the best place to start.  If they dont over see this, ask them for a contact w/ the state EPA or the UST branch.  MAKE SURE YOU USE CERTIFIED COMPANIES.... THIS IS THE EPA WE'RE TALKING ABOUT! \n\nTOTAL BILL FOR TWO 20'S  W/ 3RD PARTY ENVIRO. CONSULTANT WAS AROUND 35 G'S
