Answer to Question #89071 in Molecular Physics | Thermodynamics for Ashlin

Question

Fluid of density 2700 kg m−3 flows through a horizontal pipe that curves up into a vertical pipe as shown as shown in the figure above. If the absolute pressure in the pipe at point 1 is P1 = 160 kPa then what is the absolute pressure in the pipe at point 2, P2 (A= 0.067cm^2 H= 52cm

Answer 1

We have:

$$P_2=P_1+\rho gH$$

$$P_2=160000+(2700)(9.8)(0.52)=174000\ Pa=174\ kPa$$
