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.

Hydrostatic forces and tension in cable holding the Gate - SOLVED Example

Example:
The retaining wall in Figure 1 holds back a combination of water and mud. Considering it to have a dimension of 1 m in the perpendicular direction (i.e. out of the page) determine what the force in cable BE and the reaction forces at D will be.
