- A transformer that is 10 cm long, 6.2 cm wide, and 5 cm high is to be cooled by attaching a 10 cm by 6.2 cm wide polished aluminum heat sink(emissivity=.03) to its top surface. The heat sink has seven fins, which are 5 mm high, 2mm thick, and 10 cm long. A fan blows air at 25 degrees C parallel to the passages between the fins. The heat sink is to dissipate 12W of heat, and the base temp of the ehat sink is not to exceed 60 degrees C. Assuming the fins and the base plate to be nearly isothermal and the radiation heat transfer to be negligible, determine the minimum free-stream velocity the fan needs to supply to avoid overheating. Assume the flow is laminar over the entire finned surface of the transformer.arrow_forwardI need a mechanical engineering expert to solve this question,no Ai pleasearrow_forwardCan you give me the meaning of Combination spanner and Give Examples of Spannersarrow_forward
- HW8 A shaft fitted with a flywheel rotates at 650 r.p.m. and drives a machine. The torque of machine varies in a cyclic manner over a period of 2 revolutions. The torque rises from 650 N-m to 2200 N-m uniformly during 110° and remains constant for the following 270°. It then falls uniformly to 600 N-m during the next 100° and remains constant for the end cycle, the cycle being repeated thereafter. Determine the power required to drive the machine and percentage fluctuation in speed, if the driving torque applied to the shaft is constant and the mass of the flywheel is 180 kg with radius of gyration of 35 cm.
