In a heat treatment process, a 2-kg steel part that is initially at 1000 k, is quenched in a tank containing oil, initially at 300 k. there is negligible heat transfer between the contents of the tank and their surroundings. the steel part = 0.50 kj (kgk), = 8080 kg m3 ⁄ ⁄ ] and oil [cc = 1.95 kj (kgk), = 890 kg m3 ⁄ ⁄ ] can be modeled as incompressible substances

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.

Burgers vector is generally parallel to the dislocation line. a)-true b)-false

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?
