A power cycle operating between two reservoirs receives energy QH by heat transfer from a hot reservoir at temperature TH = 2000 K and rejects energy QL by heat transfer to a cold reservoir at TL= 400 K. For each of the following cases determine whether the cycle operates reversibly, irreversibly, or is impossible:(a) QH = 1100 kJ, Wcycle = 900 kJ.(b) QH = 1000 kJ, QL = 200 kJ.(c) Wcycle = 1400 kJ, QL = 600 kJ.(d) ? = 50%

An air conditioning system consist of a 5 cm diameter pipe, operating at a pressure of 200 kpa. the air initially enters the pipe at 15°c with a velocity of 20 m/s and relative humidity of 80%. if the heat supply throughout the process is 960 w, determine the relative humidity and the temperature at the outlet

Air flows over a heated plate Ă t a velocity of 50m/s. the local skin factor coefficient at a point on a plate is 0.004. estimate the local heat transfer coefficient at this point. the following property data for air are given: density = 0.88kg/m3 , viscosity 2.286 x 10 ^-5 kgm/s , k = 0.035w/mk ,cp = 1.001kj/kgk. use colburn reynolds analogy.
