Find C.O.P from simple vapor compression refrigeration cycle R717. The evaporation temperature is -5 degrees Celsius and the condenser temperature is 30 degrees Celsius. COP =

n industrial plant generates its own power thru heat transfer and mechanical work, from heat energy generator and turbo generator set. A bagasse fired 60 tonner water tube boiler generating 335 psi. And 330°C superheated steam. Condensates at 90°C feedwater absorbing heat at the deaerator and preheater by as much as 3 592 446 KJ/hr that supplies the steam drum at a rate of 10% higher than the steam generated. Tons steam per ton cane is 2. Superheated steam at a velocity of 25 m/sec is supplied to an impulse turbine that drives a generator producing electrical energy. Exhausted heat energy at a velocity of 20 m/sec, before undergoing heat condensations is at 800 KJ/kg.Determine the following:The Boiler Thermal Efficiency

What is the answer of the following asked: (need solution ASAP, thank you)The heat rejected in the condenser  in kJ/kg is:The net work in the turbine in kJ/kg is:

using the values given in the two evaporator refrigeration systema) Draw the T-s diagram. (evaporator output saturated steam, condenser output saturated liquid, compressor isentropic efficiency is 0.8)b) Find the coefficient of performance (COP).
