One kilogram of ice at -5°c is mixed with 2 kg of water at 18°c in an insulated copper vessel of mass 1.5 kg. at equilibrium, the vessel contains both ice and water. determine the final mass of ice in the vessel. heat capacity of water =4.19 kj/kgk, heat capacity of ice= 2.04 kj/kgk, heat capacity of copper= 0.39 kj/kgk latent heat (fusion) =335 kj/kg

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.

Carbon dioxide gas expands isotherm a turbine from 1 mpa, 500 k at 200 kpa. assuming the ideal gas model and neglecting the kinetic and potential energies, determine the change in entropy, heat transfer and work for each kilogram of co2.
