Aconstant head hydraulic conductivity test was run on a quartz sand specimen (gs = 2.65). the sample was 110 mm long with a diameter of 50 mm. the temperature of the water used to conduct the test was 22°c. after 5 minutes, the discharge under a constant head of 25 cm was 79 cm3. the mass of the solids of the sample was determined to be 385 g. calculate:

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.

Wiy doeres rere okhn a pump whon working betwon the same pressure range?

For each of the following process: a) sketch the p-v diagram, b)sketch t-s diagram, c) sketch t-v diagram, d) sketch the boundary work on one of the diagrams (a, b or c) and e) sketch the reversible heat transfer on one of the diagrams (a, b or c): 1- isobaric process from compressed liquid to superheated vapor 2- isothermal process from compressed liquid to superheated vapor 3- isentropic process from compressed liquid to superheated vapor
