1 and 2 water (r = 1005 kg / m3, m = 1.807´10-3 kg / m × s) are connected by 40 m long 2 cm long plastic pipes. Losses next to losses in the piping system may be the cause of their losses. The water level in both chambers is the same, but 1 chamber is pressurized with compressed air and 2 chambers are open to the atmosphere at 88 kPa. Calculate the absolute air lemon in 1 chamber according to the initial flow rate in the pipe 1.2 L / s.
The owners of a smallholding water their vegetable garden using collected rainwater from atank. Thetankhasadiameterofbm,itisam tall and sits on a 6 m tall stand. The inner diameter of the hose is c cm, and the hose is (20 +5d) m long. If the tank was initially filled to the brim, how long will it take before the tank is empty? Assume that there is a single ball valve (K = 0.05) in the line, and that the spray nozzle has a hole diameter that is 20 % of the diameter of the hose. You may ignore all other losses in the nozzle. a = 9 b = 8 c = 7 d = 1 Hint: Use an Excel spreadsheet or C program for the calculations.
The tank below is cylindrical and has a vertical axis. Its horizontal cross-sectional area is 10 m2. The tank has a layer of water under a layer of gasoline (S.G= 0.72). Three holes were drilled in the tank, one at the bottom of the tank, the second hole is in the water layer, 2 m from the bottom. The third hole was drilled 1S 11 in the gasoline layer 5 m from the bottom. The initial discharge velocities from the bottom and the third holes were also recorded as shown in the table below.
