A pump is used that has a Power Pb= 40HP and works with an efficiency of 85% to drive a flow rate Q of oil through the system shown in the figure. The suction pipe has a diameter D1= 10 inches and the discharge pipe has a diameter D2=8 inches; Between the suction tube and the discharge tube there is a differential pressure gauge with mercury, which shows a column h = 45 in. Find the flow

answer this ; The vertical coordinate (y-coordinate; the y-axis serves as the  axis of symmetry of the cross-section.) and horizontal  coordinate (z-coordinate) of the location where the maximum shear stress occurs in the section are  y= mm ; z= mm; The vertical distance from the location where the maximum shear stress occurs in the section to the bottom side ( AB ) of the cross section can be calculated as    Distance = mm

The force acting on the gear tooth is F=45 KN. Resolve this force into two components acting along the lines aa and bb * F. 80° 50° F_a=65.46 KN, F_b=D35 KN none of above O F_a=32.46 KN, F_b=D40 KN F_a=45.17 KN, F_b=45 KN O F_a=57.85 KN, F_b=45 KN
