Consider water at temperature 20 degrees C flowing through the following system. The reservoir surface area is 1.6 m and the cross-sectional area everywhere in the pipe is 0.05 m. Friction losses are as follows: . h12 = 7 cm hL23 = 3 cm h34 = 3 cm h45 = 4 cm Reservoir Z = 1.0 m Free jet IIK P pump Zs=unknown Pa P4 P P datum.. X 0% The pump provides 1.7 m of head (hp), and the system has reached an equilibrium with flowrate Q = 22 Liters/second. Calculate the pressure at P3. Hint: remember that we are working in gage pressure, which can be negative or positive. P3= number (rtol-0.01, atol=1e-08) pipe
