Solved Example - Cavitation and Discharge in hose/pipe

Problem:
Water is pumped from the river through a 45-mm-diameter hose having a length of 3 m . The friction factor is f = 0.028 for the hose, and the gage vapor pressure for water is -98.7 kPa. Suppose that h = 2 m . (Figure 1)



Determine the maximum volumetric discharge from the hose at C so that cavitation will not occur within the hose.

Solved Example - Height/Elevation of Pipe for Cavitation to occur

Problem: (a) Compute the discharge rate (m^3/s) of the water from the bowl if h = 30 cm, dia = 5 cm, H1 = 2 m, H2 = 7 m, p(atm) = 101. 3...
