You are filling your beer mug from a keg. the pressure in the keg is 5 psig, the filling tube from the keg is 3 ft long with 1/4 in. id, and the valve is a diaphragm dam type. the tube is attached to the keg by a (threaded) tee, used as an elbow. if the beer leaving the tube is 1 ft above the level of the beer inside the keg and there is a 2 ft long, 1/4 in. id stainless steel tube inside the keg, how long will it take to fill your mug if it holds 500 cm^3 ? (beer: μ = 8 cp, rho = 64 lbm/ft3 )

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.

The drive force for diffusion is 7 fick's first law can be used to solve the non-steady state diffusion. a)-true b)-false

An ideal otto cycle with air as the working fluid has a compression ratio of 8. the minimum and maximum temperatures in the cycle are 300 k and 1340 k. use constant specific heats at room temperature to determine (a) the amount of heat transferred to the air during the heat- addition kj/kg, (b) the thermal efficiency, and (c) the thermal efficiency of a carnot cycle ope limits. process, in rating between the same temperature
