Question

Glycerin at a temperature of 30 degrees celcius flows at a rate of 8×10−6m3/sthrougha horizontal tube with a 30mmdiameter. what is the pressure drop in pascals per100m?

Answer 1

The pressure drop in pascal is 3.824*10^4 Pascals.

To find the answer, we need to know about the Poiseuille's formula.

How to find the pressure drop in pascal?

• We have the Poiseuille's formula,

                     $Q=\frac{\pi r^4P}{8\beta l}$

• where, Q is the rate of flow, P is the pressure drop, r is the radius of the pipe, is the coefficient of viscosity (0.95Pas-s for Glycerin) and l being the length of the tube.

• By substituting values and rearranging we will get the pressure drop as,

                  $P=3.284Pascals$

Thus, we can conclude that, the pressure drop in pascal is 3.824*10^4.
