Please answer a and b thank you so much 1. a. In a diesel cycle the temperature at the beginning of compression is 870C. If r = 14, find the temperature at the end of the compression. (T2 = 761.550C) b. If the temperature at the beginning and end of the expansion are 17950C and 6770C, respectively, what is the thermal efficiency of the cycle? Assume γ = 1.40. (ηth = 59.26%)
Air within a piston-cylinder assembly executes a Carnot heat pump cycle, as shown in the figure below. For the cycle, TH = 600 K and Tc = 300 K. The energy rejected by heat transfer at 600 K has a magnitude of 1000 kJ per kg of air. The pressure at the start of the isothermal expansion is 325 kPa. p-v diagram for a Carnot gas refrigeration or heat pump cycle.
