Thermodynamics: An Engineering Approach
- 6–88 In tropical climates, the water near the surface of the ocean remains warm throughout the year as a result of solar energy absorption. In the deeper parts of the ocean, how- ever, the water remains at a relatively low temperature since the sun's rays cannot penetrate very far. It is proposed to take advantage of this temperature difference and construct a power plant that will absorb heat from the warm water near the sur- face and reject the waste heat to the cold water a few hundred meters below. Determine the maximum thermal efficiency of such a plant if the water temperatures at the two respective locations are 24 and 3°C. 24°C Boiler Осean Pump Turbine Condenser 3°Carrow_forwardTwo parallel shafts whose centers are 10 meters apart are connected by an open belt drive with a V-belt with a groove angle of 30°. The diameter of the larger pulley is 1000 mm and that of the smaller pulley is 400 mm. The smaller pulley is running at 1000 rpm to deliver 10 kW of power. The mass of the belt is 1 kg/m. Taking centrifugal tension into account, determine the minimal cross-sectional area if the allowable tensile stress of the belt is 5 MPa. The coefficient of friction between the belt and the pulleys is 0.25.arrow_forwardA shaft fitted with a flywheel rotates at 350 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 350 N-m to 3500 N-m uniformly during 90° and remains constant for the following 180°. It then falls uniformly to 850 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 300 kg with radius of gyration of 450 mm.arrow_forward
