Concept explainers

Slope and Deflection

The slope in a deflected beam is described as an angle in radians made by the tangent of the section with the original axis of the beam. The deflection at any point on the axis of the beam is defined as the lateral displacement of the point before and after loading.

Problem-3: A centrifugal pump lifts water against a static head Az = EN m. The pipe setup has a constant diameter of 0.08 m, major losses in the suction side h, = EN3 m and in the discharge side hLD is 3 m. The pump impeller has a diameter of 0.15 m, exit width of 0.015 m, exit blade angle of 22° and speed of N = 20EN rpm. The hydraulic efficiency is 0.85. If the flow at the entrance is radial, find the discharge, pump head, atmospheric pressure Pat, Vapor pressure P, and maximum allowable height of the pump from the feeding tank water surface elevation if the pump is operating under T 25 °C at altitude H= 20EN m. %3D 0, = NPSHR/Hp =1.21×10³N = (P EN=62 Is-mx at-abs-P,)/Y-hLsT -0H, Pa-abs /Y = 10.33(1– 2.256x10-H)56 P,ly = e14.29-3985(T+233.4))
