you have develope a super heat sotrage fluid and now need to determine its heat of vapoirization you set up an experiment with 60m cylindrical copper tube. the fluid enters the tube at 130 C at 100% vapor and exits at saturated liquid. the outer surface is exposed to water at 25C with a heat transfer coefficient of 200 W/m^2k. The inner surface heat transfer coerfficent is 350 W/m^2k. The inner tube diameter is 20 cm and the tubing is 2cm thick. If the mass flow rate is 0.1 kg/s. what us the heat of vaporization.

Amass of 1.5 kg of air at 120 kpa and 24°c is contained in a gas-tight, frictionless piston-cylinder device. the air is now compressed to a final pressure of 720 kpa. during the process, heat is transferred from the air such that the temperature inside the cylinder remains constant. calculate the boundary work input during this process.

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.

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?
