Heptane (c7h16) is burnt with 10 per cent less than the stoichiometric amount of air. determine the amount of substance of each product per kilomole of heptanes burnt wher the products temperature is 2000 k. at this temperature the water gas dissociation constant (ph2o)(pco)/ ph2) (pco2) is 4.259.

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.

Fluids at rest possess no flow energy. a)- true b)- false

During a steady flow process, the change of energy with respect to time is zero. a)- true b)- false
