Pascle is the unit of pressure loss.

You could use Bernoulli's equation between two points to solve for the velocity of the fluid in question.  Area of the pipe (or area of the cross section of what the fluid is flowing through) multiplied by the velocity will give you the discharge.  If you aren't familiar with Bernoulli's equation, see the source below.

I think you can use Bernoulli's equation to predict the difference in pressure from one area of the hose to the other and, therefore, the pressure drop:\n\nP = (flow rate * 8 * viscosity * length of hose) / (pi * hose radius^4)\n\nNot sure if it works though...typically used for fluids...

Broad. Less pressure. Same work.

Pascal's Principal shows how to calculate pressure. The unit of pascals (used to show pressure) is one newton of force per square meter and to calculate it you divide force by pressure.\n\nso Pascal's Principal is: \n\nforce/area= pressure or newtons/meters2=pascals

When a stem is cut, water surges out of the stem for some time.  This proves that there is force which acts on the water.

The flow volume rate remains constant.  Since the output pipe is half the diameter of the input pipe, the cross section area is 1/4 times as large and the linear flow rate is 4 times that of the input pipe, or 400 ft/sec.\nWith no friction the pressure drop should be zero so the exit pressure is 200 psf.

The pressure P(in pounds per square foot) from wind blowing at S miles per hour is given by P=.00256e^2.\n\nDon't you think the formula ought to have S in it?

insufficient data, you need force with which the body is being dragged.

Decrease because there is less oxygen. I think.

it *is* Bernoullis principle.  Think of pressure as a form of potential energy and velocity as kinetic energy.  The total energy must remain constant so, if one increases, the other must decrease.\n\n\nDoug

It is of a pressure equal to 0.6 ­ 1.1 atmosphere (600 ­ 1100 g/cm 2 ) at sea level (8.5 lbs/sq in 15.6 lbs/sq in)
