A tank of water is 10 ft in diameter and contains a water column of 10 feet. The water has a density of 62.3 lbm/ft3. What is the pressure, in psia, at the inlet to a pipe that is at a depth of 5 feet?

A pipe has an inner diameter of 36 inches. Water flows through the pipe at an average velocity of 150 feet per second. What is the volumetric flow rate of water in the pipe?
A pipe has an inner diameter of 30 inches. Water flows through the pipe at an average velocity of 35 feet per second. If the density of the water is 62.4 lbm/ft3, what is the mass flow rate?

A pipe that has a diameter of 48 inches gradually reduces to a diameter of 24 inches. The density of the fluid in the pipe is constant at 62.4 lbm/ft3. If the system is in a steady-state flow condition and the flow velocity is 45 ft/sec in the 48-inch section, what is the flow velocity in the 24-inch section?
