1) Calculate and plot the variations of the gas pressure, liquid
level in the accumulator tank,
and the liquid discharge rate in kg/s as the liquid level falls
from h = 5 m to 1 m if the initial
gas pressure in the accumulator tank is 1,500 kPa at t = 0. Water
is discharged to the
atmosphere through a discharge nozzle with 𝑨𝑨𝟐𝟐 = 𝟎𝟎.
𝟎𝟎𝟎𝟎𝟎𝟎𝒎𝒎𝟐𝟐.
2) The accumulator tank is again closed at the top and contains
water at a height of 5 m as well
as a gas with an initial pressure of P1 = 1,500kPa. Water is now
discharged to a closed
receiver tank with an initial volume of 𝓥𝓥𝒈𝒈 = 100m3 initially at
P2 = 200 kPa. As the water
is discharged into the receiver tank, the pressure P2 in the
receiver tank will increase with
time. Calculate and graphically show how the accumulator gas
pressure P1, receiver tank
pressure P2, liquid height h and discharge velocity 𝑉𝑉2 change with
time.

Water is discharged to the atmosphere through a discharge nozzle with A2 = 0.001m2. 2) The accumulator tank is again closed at the top and contains water at a height of 5 m as well as a gas with an initial pressure of P, = 1,500kPa. Water is now discharged to a closed receiver tank with an initial volume of V, = 100m initially at P2 = 200 kPa. As the water is discharged into the receiver tank, the pressure P2 in the receiver tank will increase with time. Calculate and graphically show how the accumulator gas pressure Pl, receiver tank pressure P2, liquid height h and discharge velocity V2 change with time. The gas volume in the receiver H-h P1 = 1,500 kPa tank decreases from V, - 100 m3 with time as discharged water Pi begins to fill up this receiver tank. 21 at t=0 H V2 22 Initially empty receiver tank with V=100 m and P2 = 200 kPa at t = 0
