An inclined tube manometer with a reservoir is used to measure the pressure gradient in a large pipe carrying oil (sg = 0.91). the pipe is inclined at an angle of 60° to the horizontal, and flow is uphill. the manometer tube is inclined at an angle of 20° to the horizontal, and the pressure taps on the pipe are 5 inches apart. the manometer reservoir diameter is eight times as large as the manometer tube diameter, and the manometer fluid is water. if the manometer reading (l) is 3 inches and the displacement of the interface in the reservoir is neglected, what is the pressure drop in the pipe in (a) psi; (b) pa; (c) in. h2o? what is the percentage error introduced by neglecting the change in elevation of the interface in the reservoir?

Apump is used to circulate hot water in a home heating system. water enters the well-insulated pump operating at steady state at a rate of 0.42 gal/min. the inlet pressure and temperature are 14.7 lbf/in.2, and 180°f, respectively; at the exit the pressure is 60 lbf/in.2 the pump requires 1/15 hp of power input. water can be modeled as an incompressible substance with constant density of 60.58 lb/ft3 and constant specific heat of 1 btu/lb or. neglecting kinetic and potential energy effects, determine the temperature change, in °r, as the water flows through the pump.
