26.3-2. comparison of differential and flash distillation. a mixture of 100 kg mol that contains 60 mol % n-pentane (a) and 40 mol % n-heptane (b) is vaporized at 101.32 kpa pressure under differential conditions until 40 kg mol are distilled. use equilibrium data from example 26.3-2. what is the average composition of the total vapor distilled and the composition of the remaining liquid? if this same vaporization is done in an equilibrium or flash distillation and 40 kg mol are distilled, what is the composition of the vapor distilled and of the remaining liquid?

The temperature of air decreases as it is compressed by an adiabatic compressor. a)- true b)- false

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.
