4. An operating parameter often used by power plant engineers is the heat rate. The heat rate isdefined as,HRQbiolerWnetwhere Qbioler is the heat transfer rate (Btu/h) to the water in the boiler due to the combustion of afuel and Wnet is the net power (kW) delivered by the plant. In comparison, the thermal efficiencyof the power plant is defined as,nthWnetQbiolerwhere the numerator and denominator have the same units. Consider a power plant that isdelivering 1000 MW of power while utilizing a heat transfer rate of 3570 MW at the boiler.Determine the heat rate and thermal efficiency of this power plant.

This is Problem 13 of Chapter 3 in Sustainable Energy by Richard Dunlap, 2nd Edition. I need help solving it: A coal-fired generating station has an efficiency of 38% and produces an average electrical output of 1000 MWe.(a) How much coal does it burn per second (kg/s)? Assume the coal is bituminous.(b) How much heat (in joules) is released to the environment per second?(c) How many liters of water at 20°C could the heat in part (b) boil (at STP) per second? For c, here is my idea: use Q = mc(change in T). Here change in T is (100 C - 20 C) or 80 C and c = 4200 J/(kg C) so I can solve for m. Question: I need the density of water to find liters, but density changes with temperature. So, do I use the regular 1000 kg/m^3 or something else?
I have been working on this problem for a while and keep getting wrong answers with many different meathods how do I solve for Q0 here?
A group is considering installing a solar power station and has asked you for your recommendation if it should be a photovoltaic system or a solar thermal system. At this stage you are asked not to include cost factors. The single point design condition they have given you is for an incident solar radiation on the collector of 550 W/m2, a surrounding temperature of 18 C. The dead state for this problem should be taken as To = 291 K, Po = 1 bar. You can perform your analysis at steady state conditions. In addition to determining the power output and first law efficiency of the options, you have been requested to determine the exergy destroyed for each of them. The photovoltaic system has an efficiency of 0.15 defined as the power output/incident solar radiation. The basic photovoltaic collector is 1.1 m2 and losses heat from both the front and back surface. The edge area can be neglected. The convective heat transfer coefficient is 10 W/m2 K. The inverter and signal…

The heat loss from a chicken coop (chicken house) is K(Tnside - Totside) during the winter, where K is 1.5 kW/K. The chicken coop temperature can vary between 15 °C and 25 °C without harming egg production. A heat pump with a coefficient of performance of 40% of that of a reversible heat pump is used to heat the chicken coop. What are the minimum power requirements if the outside temperature is -5 °C? .
Don't Copy, Is the answer is 10.53? Please do verify fast with explanation.
