A constant head permeability test has a soil sample length in the direction of flow of350 mm, a sample cross sectional area normal to the flow direction of 125 cm2, and ahead loss through the sample of 420 mm. The soil sample is a medium dense sand with avoid ratio of 0.61. During a 3 minute test period, 580 cm3 of water flowed through thesample. (a) Sketch the Constant Head Permeameter and label the sketch with theappropriate dimensions given above. (b) Determine the Hydraulic conductivity, k, incm/sec, and the seepage velocity (not just apparent velocity).

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.

Aplate clutch has a single pair of mating friction surfaces 250-mm od by 175-mm id. the mean value of the coefficient of friction is 0.30, and the actuating force is 4 kn. a) find the maximum pressure and the torque capacity using the uniform-wear model. b) find the maximum pressure and the torque capacity using the uniform-pressure model.

You are making beer. the first step is filling the glass carboy with the liquid wort. the internal diameter of the carboy is 15 in., and you wish to fill it up to a depth of 2 ft. if your wort is drawn from the kettle using a siphon process that flows at 3 gpm, how long will it take to fill?
