5-9 A 0.75-m³ rigid tank initially contains air whose den- sity is 1.18 kg/m³. The tank is connected to a high-pressure supply line through a valve. The valve is opened, and air is allowed to enter the tank until the density in the tank rises to 4.95 kg/m³. Determine the mass of air that has entered the tank. 2.83
The flow is opened to the atmosphere at point D which is fed by a very wide reservoir that has a water surface elevation of (5+) meters as shown in the figure given below. Elevation of the horizontal axis BC is 1 meter. At sections AB the diameter of the pipe is (0.2+- meters and CD the diameter of the 100 pipe is (0.3+: meters. The flow is ideal (inviscid) and absolute atmosphere pressure is 9.81 N/cm?. Considering the pipe's diameter is (0.15+; m at section BC, find the discharges and the 100 а. velocities of the flow at other sections (AE, EB, BC, CF, FD). Draw the energy and hydraulic grade lines of the system. b. Assuming the system discharge is constant and has the value you have found in (a), calculate the minimum pipe diameter that the section BC can take and draw the energy and hydraulic grade lines of this situation. Note: Absolute vapor pressure of water is 2.26 kN/m?. 10 A E 2.5 D B m
