The flow rate of water is measured using a Venturi flow meter (Figure 1) which is located in ahorizontal pipe section. Apply the Bernoulli equation to calculate flow rate of water in Lpm given the following data. The differential pressure reading, P1-P2 = 1.5 cm Hg.

Data: Density of water 1 g/mL DPI: Differential pressure indicator, cm Hg Density of mercury = 13.6 g/mL Diameter of inlet, D1 = 10 cm Diameter of throat = 4 cm Assume friction losses for the system are negligible.
