Question

Air 250 kPa Problem6 A tall tank has an orifice (circular opening) located 2.5 m below the water surface. The tank is closed with an ABSOLUTE pressure of 250 kPa. Atmospheric pressure is 100 kPa. (a) Neglecting frictional effects, determine the flowrate out of the tank. (b) As the tank empties, will the flowrate increase, decrease, or remain the same? Prove your answer with equations and words. Assume the air pressure in the tank remains constant. 2.5 m 10 cm
