A large tank of height h 4m water has a hose connected to it as shown in figure The tank is sealed at the top and has compressed air between the water surface the top When the water height h is 3m the gauge pressure of air is P 1 10 N m Assume that the air above the water surface expands isothermally What is the velocity of flow out of the hose when h has decreased to 2m Assume ideal fluid flow P 10 N m atm m h 4m P h lm
