The Van der Waals equation of state is for real gases that do not behave as ideal gases. This equation is a cubic equation of state, meaning that it gives 3 volume roots. One root will be close to the value of the constant b liquid root) and the other (vapor root) can best be estimated using the ideal gas value of RT/P. A third root is meaningless. P= RT/V-b - a/V^2 where b= RTc/8Pc and a= 27R^2Tc^2/64Pc^2

For methane at 100°C and 15 bar, determine the gas root of Volume using the Van der Waals EOS. You will need to use goalseek function to determine the root. For convenience, the Tc of methane is 190.6 K and Pc = 46.1 bar. Calculate the volume value in liters.

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.
