You decide to build a new super-space-time-tunnel-vehicle to escape the fast approaching viruses and zombies. Since you had to move fast all you had is a Dual Cycle Engine to power your new space-vehicle. The compression ratio is 14. The air is at 1 bar pressure and 27 degrees Celsius at the intake and at 1927 degrees Celsius after the two-stage heat-addition process (after both constant volume and constant pressure heat addition). The total amount of heat added is 1520.4 kJ/kg. Assume variable specific heats for air (VSH) Find:

(a) List ALL assumptions (detail Standard Air assumptions) and show a P-v and T-S diagram of your process.
(b) The fraction of heat (in %) transferred during the constant volume part of heat addition.
(c) The thermal efficiency of your cycle (in %).

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.

Water in a partially filled large tank is to be supplied to the roof top, which is 8 m above the water level in the tank, through a 2.2-cm-internal-diameter pipe by maintaining a constant air pressure of 300 kpa (gage) in the tank. if the head loss in the piping is 2 m of water, determine the discharge rate of the supply of water to the roof top in liters per second.
