Water at 65C flows through a 75-mm-diameter orifice

installed in a 150-mm-i.d. pipe. The flow rate is 20 L/s.

Determine the pressure difference between the corner taps.

A smooth 200-m pipe, 100 mm diameter connects two

reservoirs (the entrance and exit of the pipe are sharpedged). At the midpoint of the pipe is an orifice plate with

diameter 40 mm. If the water levels in the reservoirs differ by

30 m, estimate the pressure differential indicated by the

orifice plate and the flow rate.
