Water at 20 °C is pumped at constant rate of 9 m*/h from a large reservoir resting
on the floor to the open top of an experimental absorption tower. The point of
discharge is 5 m above the floor, and frictional loss in the 50 mm pipe from the
reservoir to the tower amount to 2.5 J/kg. If the pump can deliver 0.1 kW,
determine the height of the water level in the reservoir.

Water flows at the rate of 0.015 ۸ through a 100 mm diameter orifice used in a
200 mm pipe. What is the difference in pressure head between the upstream
section and venacontracta section? Take co-efficient of contraction 0.6 and
சே.

Sketch and explain the estimation of flow rate using Rectangular and Triangular

weirs.
