1 The flow is steady and incompressible. 2 The
entrance effects are negligible, and thus the flow is fully developed. 3
The flow is turbulent so that the tabulated value of the loss
coefficients can be used (to be ver
A solar heated water tank is to be used for showers using gravity
driven flow. For a specified flow rate, the elevation of the water level
in the tank relative to showerhead is to be determined.

Calculate minimum gage pressure required at section 1.
If the device were inverted what would be the minimum pressure at section 1 to
maintain nozzle velocity at 20 m/s.
