If the intermediate and output shafts were to be 100 inch apart (still parallel), replace gears 3 and 4 with pulleys and find the right polyamide flat belt size (belt type and width) to achieve the desired torque and speed at the output shaft. Use a design factor of 1.1. The belt cannot be wider than 10 inches (if the designed belt width is larger than 10 inch, you can choose a stronger belt or change pulley diameters). Justify your design choices.

An ideal vapor-compression refrigeration cycle is employed to maintain a building temperature of 23°c when the outside temperature is 37°c. the cycle operates at steady state using ammonia as the working fluid. the mass flow rate of the refrigerant is 15 kg/min. the refrigerant enters the compressor at 1.5 bar and 10 °c. the condenser pressure is 20 bar and the temperature at the condenser exit is 45 °c. determine (a) the compressor power in kw. (b) the refrigeration capacity in tons. (c) the coefficient of performance. d) the maximum theoretical coefficient of performance.
