An orifice meter is to be used to measure the flow rate of propyl alcohol at 25°C through a PVC plastic pipe, 40 mm OD × 3.0 mm wall. The expected range of flow rates is 1.0 m3/h to 2.5 m3/h. Specify the orifice diameter to obtain β=0.3 and determine the range of reading for the mercury manometer for the given flow rates. Also, plot the graph of power consumption of meter versus flow rate.
