Calculate the volume rate of flow of water through a pipe of 100 mm dia. When measured by (a) An orifice plate of orifice size 50 mm dia and (b) venture tube of throat size 50 mm dia. The recorded dP. 250 pa. The density of water is 1000 kg/m3. Assume orifice Cd equal to 0.6 and venture cd equal to 0.9.
