3. A tank contain water at 60oF (kinematic viscosity 1.22 * 10-5 ft2/s). A nominal 6 schedule 40 horizontal steel pipe exits the tank through a square edged entrance. 150 ft from the tank there is a valve, k = 2.5, 200 ft further down the pipe there is a sudden contraction, K = 0.25 (use downstream velocity) to a nominal 4 schedule 40 steel pipe. 50 ft later the pipe exits to the atmosphere through a 3 in diameter nozzle, k = 0.2 (use exit velocity). If the water level in the tank is 40 ft above the outlet nozzle, determine the flow rate. 4. Determine the values for the Energy Grade Line and the Hydraulic Grade Line for the tank and pipe system of problem 3. Plot the EGL and HGL. 6. Nominal 8, schedule 40 steel pipe carries 2.0 cfs. Verify that the Hazen Williams equation V = 1.32 Ch R0.63 S0.54 gives the equation hL = (4.73 L Q1.852 )/ (Ch1.852 D4.87) Determine the energy loss per 100 ft. The Hazen Williams coefficient is 110. 7. Determine the size of cast iron pipe needed to carry 2.5 cfs between two tanks 240 ft apart if the water surface elevation difference is 15 ft. New cast iron pipe has a Hazen Williams coefficient of 130, 10 year old cast iron pipe the coefficient is 110, 20 years old it is 95, 30 years old it is 83, 40 years old it is 75. Plot the actual flowrate versus time for 40 years.
