A binary mixture of mole fraction z1 is flashed to conditions T and P. For the following, determine the equilibrium mole fractions x1 and y1 of the liquid and vapor phases formed, the molar fraction V of the vapor formed, and the fractional recovery R of species 1 in the vapor phase (defined as the ratio for species 1 of moles in the vapor to moles in the feed). Assume that Raoult’s law applies. Ethanol(1)/1-propanol(2), z1 = 0.25, T = 360.00 K, and P = 81.06 kPa

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.
