Question 1 The figure below shows a simple water pipe network. Relevant pipe properties are given in the figure and table below. The major losses of the pipes can be calculated by Darcy Weisbach equation. The friction factor () for all pipes is 0.015. Assuming that minor losses in the pipe network can be ignored and the pipe network is on a horizontal plane, determine the flow rates in all pipes using Hardy Cross method. Also, calculate the pressure head...

Water with a velocity of 5m/s flows through the parallel concert piping system with a relative roughness of 0.04 shown below. The entrance diameter is 4m, the length of the parallel pipes is 40 m and L/d for the pipes at A and B is 10m. Here the pressure at the inlet of the system is measured by a mercury manometer directly below it. Given your understanding of the flow of incompressible fluids,notice the squared inlet edge and four standard...

Problem 1 (30): Water (density p 999 kg/m') flows through a pipe bend and constriction as shown in the schematic. The pipe section is connected to input and output pipes at loc ations A and B. the inlet point A is located 1 m higher in elevation compared to the exit point B. The total loss d ue to pipe friction, bend, and constriction can be approximated as EU = etY2 with et = 2.1 2 Find the total force...

Water flow in a pipe and then exit through a bended nozzle as shown in Figure 3. The nozzle is connected to the main pipe using a flanged joint at (1). The diameter of the pipe is D1 10 cm and is constant, whilst the diameter at the outlet section of the nozzle (2) is D2 3 em. The flowrate of the water is Q = 15 liter/s and the water pressure at the flange is Pi 230 kPa. By...
