Unformatted text preview: Pipe Problems 1. Water (V =1.1_4x10"6lm2/s) flows at q’ 2 0.05m3 /S in the 10 cm diameter pipe whose roughness is e=0.046mm. I If the air in the tank is 191 — pa = ZOOkPa, What is the work rate of the pump? 2. A pressure 191 — pa =136kPa forces fluid through the 1.5mm diameter tube with a velocity of 0.5m/s. The density of the fluid is p =1150kg/1m3 . What is the V viscosity of the fluid? 35 The pump delivers 20kW to cause a flow rate of 140 US of ‘ water. What is the pressure p2 in the air in the top of tank 2. .- 75$ 7 p, =2 kPa gage Commercial sieel pipe Water T=15”C 1/ =0.o1141x1’0~‘ mZ/s Fionw: R 711 4) The flow rate through the system 'is q' = 0.4m3 / s.
