A large, enclosed (pressurized) cylindrical tank 3 meters high contains 2.8 meters of oil (s.g. = 0.87). An orifice (Cc = 0.75, Cv = 0.95) at the bottom of the tank with a diameter of 25 mm was opened and a volume of 120 liters was collected after 30 seconds. Determine the velocity of the jet at the venna contracta and the pressure of air above the oil. Actual Velocity = m/s Pressure of air = kPa

Question

A large, enclosed (pressurized) cylindrical tank 3 meters high contains 2.8 meters of oil (s.g. = 0.87). An orifice (Cc = 0.75, Cv = 0.95) at the bottom of the tank with a diameter of 25 mm was opened and a volume of 120 liters was collected after 30 seconds. Determine the velocity of the jet at the venna contracta and the pressure of air above the oil.

Actual Velocity =            m/s

Pressure of air =            kPa
