A 20 hp (14.9 kW) pump is transporting liquid ethanol from a storage tank to the top of a separation column. The pump operates with 75% efficiency at a flowrate of 42 kg/s. The tank is open to atmospheric pressure with a liquid level maintained at 1.5 m. The inlet to the column is located 15 m above ground and the fluid velocity at this point is 1.2 m/s. Assuming negligible friction losses, what is the pressure at the top of the column? Separation Storage Tank
