60 degree F water flows through a horizontal turbine. The water speeds at the turbine inlet and the turbine outlet are identical. The water gage pressure at the turbine inlet is 46.4 psi while that at the outlet is 12.2 psi. Assume water frictional losses through the turbine are negligible. Deterimine the shaft work rate in ft*lb per slug of water passing through the turbine. Answer with a positive number if mechanical energy goes into the water and a negative number if mechanical energy comes out of the water as it passes through the turbine.
pleaseee solve it need urgent Consider a turbocharged SI engine, with an intercooler (i/c), as shown in the Figure for Q 2 below. The turbine of the turbocharger is driven by the exhaust gases first, thereby producing power to drive the turbo-compressor. The exhaust gases leaves the turbocharger turbine in the exhaust system of the engine after serving its purpose. The turbo-compressor and the turbocharger turbine are mounted on the same shaft. For a certain engine load and throttle positioning, the conditions are given as follows: Turbo-compressor air inlet: Pressure is 100 kPa, temperature is 30°C, and the mass flow rate is 0.10 kg/s. Turbocharger turbine inlet: Pressure is 170 kPa and the temperature is 650° Turbocharger turbine exit (engine’s exhaust system): Pressure is 100 Assume that both the turbine and the compressor are running at 120,000 rev/min and there is no entropy generation in them, and they have the same mass flow rates.
