5. A power cycle receives energy QH by heat transfer from a high temperature energy source at TH = 2000 K and rejects energy QL by heat transfer to a low temperature energy sink at TL = 400 K. For each of the following cases determine whether the cycle operate reversibly, irreversibly, or is impossible.

(a) QH = 1200 kJ, Wcycle = 1020 kJ.

(b) QH = 1200 kJ, QL = 240 kJ.

(c) Wcycle = 1400 kJ, QL = 600 kJ.

(d) efficiency = 40%.

A heat engine receives an amount of energy Qh= 790 kJ by heat transfer from a high temperature thermal reservoir at Th=950 K. Energy is rejected by heat transfer to a lower temperature thermal reservoir at T1=590 K. If waste heat in the amount of Q1=160 kJ is rejected to the low temperature thermal reservoir during each cycle. a) Solve for the maximum theoretical efficiency that an engine in this situation could operate with. ANSWER: 0.379 b) Solve for actual...

A simple steam power cycle uses solar energy for the heat input. Water in the cycle enters the pump as a saturated liquid at 40°C, and is pumped to 2 bar. It then evaporates in the boiler at this pressure, and enters the turbine as saturated vapour. At the turbine exhaust the conditions are 40°C and 10% moisture. The flow rate is 150 kg/h. Determine (a) the turbine isentropic efficiency, (b) the net work output (c) the cycle efficiency, and...

A steam power plant receives heat from a furnace at a rate of 280 GJ/h. Heat losses to the surrounding air from the steam as it passes through the pipes and other components are estimated to be about 8 GJ/h. If the waste heat is transferred to the cooling water at a rate of 145 GJ/h, determine (a) net power output and (b) the thermal efficiency of this power plant

The rate of heat transfer, Q [energy/time = power] through a pipe wall between a fluid and the surroundings depends on fluid properties: density (ρ), viscosity (μ), specific heat (cp [energy/temperature/mass]); and also on pipe and flow properties: the length (l), diameter (D), and thermal conductivity (λ [power/length/temperature]) of the pipe, fluid mean velocity (V), and the temperature difference (ΔT) between the pipe wall and the surroundings. Use dimensional analysis to express this system in terms of dimensionless numbers. The...

A steam power plant operates with a boiler that is heated from a heat source at 457 °C and produces 450 ton/hr. of steam. The steam leaves the boiler at 425 °C and 4 MPa. The steam reaches a turbine at 375 °C and 3 MPa and leaves it at 50 kPa with 4% liquid water. This mixture is flown into a condenser that rejects the heat into a river at 17 °C. Water leaves the condenser at 50 kPa...

if you transfer heat energy to a perfectly insulated cup of some liquid (no heat energy can be transferred in or out through the walls) what determines how much the temperature changes? Does it depend on how much heat energy you transfer, how much liquid there is in the cup, what the liquid is, or what the initial temerpature of the liquid is? Which of these factors do you think make a differnce in how much the temperture rises?
