5. (a) A water fountain is to be installed at a remote location by attaching a 25-mm- diameter cast iron pipe directly to a water main through which water is flowing at 20 C and 450 kPa (abs). The entrance to the pipe is sharp-edged, and the 15-m-long piping system involves three 90 smooth flanged bends, a fully open gate valve, and an angle valve with k = 5 when fully open. If the elevation difference between the pipe and the fountain is negligible, determine the water flow rate of the piping system. Given, the kinematic viscosity of water at 20C is 1.004 x 106 m/s. [Hint: Show a single iteration with initial guess Q = 2.0 L/s] 15 m d=25 mm Water main 450 kPa - (20) Fig. for Q. 5(a) (b) With neat sketch, derive an expression for minor loss due to sudden enlargement. Also comment on the value of loss coefficient in case of no area change and discharge into reservoir from the expression. (15) Please solve both of the problem in detail,i badly need its solution.I need the solution and proof in detail, sometimes some chegg experts deliver only the processes in a very short way which is very difficult to understand,so i kindly request you to write all the steps and calculations and to draw all the necessary figures. I request you again not to skip any step. 5.
