4. For the system shown in the figure below, estimate the diameter of the pipe if the pressure at section 2 cannot exceed 135 kPa, g. Water at 20C is discharging through the system at a rate of 0.2 m/s. The length of the pipe is 115 m, and the equivalent sand roughness is 0.25 mm. The pump head is given by hp =36-1402. The head h = 30 m. Neglect minor losses. [10] Hint: Follow class problem for finding diameter. Use iterative solution. Remember the pipe continues beyond the exit point. 2 h 5. For the similar system as shown in the last problem, find the discharge through the system, if the pipe diameter is 30 cm. [10] Hint: Follow class problem for finding discharge. Use iterative solution. 4. For the system shown in the figure below, estimate the diameter of the pipe if the pressure at section 2 cannot exceed 135 kPa, g.
