Mcarbon 12 kg/kmol, Maydrogen = 1 kg/kmol and Cp(Methane) 2.2537 kJ/kg.K (i) Determine the specific gas constant for methane. (ii) Calculate the change in entropy during the process. (iii) Determine the work done. = [6 marks] (c) An air conditioning unit with COP = 8 removes heat from a room to the atmosphere at a rate of 2 kW. Assuming electrical and mechanical efficiencies are 100%, determine the rate of heat transfer to the atmosphere and the required power input. [3 marks] (d) 4 kg of a gas undergoes the cycle in Figure Q1(d). Describe each process in the cycle and calculate the net work.

A lightweight drone (1.00 kg) is launched at 800 m high and moves upward at a constant velocity (while ignoring the effects of gravity only on the drone). The balloon, when measured at a horizontal distance from you, is about 1600 m away from you. At the moment when the drone moves, you shoot a bullet (weight =180 g) with an initial velocity of 1009 m/s at a fixed angle a, where sin a=3/5 and cos a= 4/5. (g = 9.8 m/s?) (10 pts each) a. How long does it take for the bullet to collide with the drone? b. At what height will the bullet hit it? Page 1 of 2 542 words 170% PC A O 4) 6:51 PM
