The elasticity and dimensions of a pipe are such that the celerity of pressure wave is 975 m/s. The pipe diameter is 1.2m and a valve is located 600m downstream. Water is flowing initially at 0.85 m³/s. (a) Find the water hammer pressure for instantaneous valve closure. (b) what is the approximate water hammer pressure if the valve is closed in 4 sec. (c) What is the water-hammer pressure if the valve is manipulated so that the flow drops almost instantly from 0.85 m³/s to 0.28 m³/s.

i) Which of the following statements about a straight horizontal pipe of 6 inch diameter pressurized pipe carrying water is incorrect? i) The EGL and HGL are parallel to each other. ii) The friction head is equal to the loss in pressure head. iii) The velocity head gradually decreases from the beginning to end of the pipe. iv) The EGL (or) TEL is above the HGL. Answer: ii) Water flows from a 0.75 m pipe into a 1 m pipe. If losses are neglected then the 1 m diameter pipe will most likely (i) Have higher velocity than 0.75 m pipe (ii) Be at the same pressure as the 0.75 m diameter pipe (iii) Be at a higher pressure than 0.75 m pipe (iv) Be at a lower pressure than 0.75 m pipe.

Oil is being transported at a rate of 20gal/min through a 2-in schedule 40 steel pipe (ID = 2.067in). The oil has a viscosity of 20cP and a specific gravity of 0.85. The line is slanted, and the static pressure at one point in the line is 45 psig. Calculate the static pressure (in psig) at a location in the line 200 feet further along flow direction and 50 feet lower in elevation.

Answer the first question
Need only a handwritten solution only (not a typed one).
Question 7 2 pts A pipe connected in series has the following roughness or friction coefficients: Pipe 1 C = 100 (Hazen-Williams) Pipe 2 n = 0.015 (Chezy-Manning) Pipe 3 f = 0.020 (Darcy-Weisbach) All pipes have a diameter of 400mm, length of 1 kilometer, and flow rate of 150 L/s. Determine the headloss on Pipe 3 in meters.
