Whether the following statement is true or false: Factors that may allow one to model a control volume as having negligible (zero) heat transfer includes the following: (1) The outer surface of the control volume is well insulated, (2) The outer surface area of the control volume is too small to permit effective heat transfer, (3) The temperature difference between the control volume and its surroundings is so small that the heat transfer can be ignored, (4) The working fluid passes through the control volume so quickly that there is not enough time for significant heat transfer to occur.

Q4/ A compressor is driven motor by mean of a flat belt of thickness 10 mm and a width of 250 mm. The motor pulley is 300 mm diameter and run at 900 rpm and the compressor pulley is 1500 mm diameter. The shaft center distance is 1.5 m. The angle of contact of the smaller pulley is 220° and on the larger pulley is 270°. The coefficient of friction between the belt and the small pulley is 0.3, and between the belt and the large pulley is 0.25. The maximum allowable belt stress is 2 MPa and the belt density is 970 kg/m³. (a) What is the power capacity of the drive and (b) If the small pulley replaced by V-grooved pulley of diameter 300 mm, grooved angle of 34° and the coefficient of friction between belt and grooved pulley is 0.35. What will be the power capacity in this case, assuming that the diameter of the large pulley remain the same of 1500 mm.
