Activity on Major and Minor Losses in Pipes 1. A 20-mm diameter commercial steel pipe, 30 m long is used to drain an oil tank. Determine the discharge when the oil level in the tank is 3 m above the exit of the pipe. Neglect minor losses and assume f=0.12. 2. A 600-mm diameter pipe connects two reservoirs whose difference in water surface elevation is 48 m and flows at a rate of 861 L/s. The pipe is 3500 m long and has the following pipe fittings: 2 globe valves, 4 short radius elbows, 2 long radius elbows, and one gate valve half open. The values of K for pipe fittings is given below: K Pipe fitting Globe valve 10 Short radius elbows 0.9 Long radius elbows 0.6 Gate valve, half open 2.06 What is the total head loss through the pipe in m if f=0.015? 3. Oil, with p = 950 kg/m³ and v=0.00002 m²/s, flows through a 300-mm diameter pipe that is 100 m long with a head loss of 8 m. ε/D = 0.0002. Calculate the flow rate.
