A hot-water stream at 80°C enters a mixing chamber with a mass flow rate of 0.56 kg/s where it is mixed with a stream of cold water at 20°C. If it is desired that the mixture leave the chamber at 42°C, determine the mass flow rate of the cold-water stream. Assume all the streams are at a pressure of 250 kPa. The enthalpies are 335.02 kJ/kg, 83.915 kJ/kg, and 175.90 kJ/kg. The saturation temperature at a pressure of 250 kPa...

A solution of NaOH in water flows in a stream, and the mass flow rate of the stream is suddenly increased. For each of the following properties of the stream, indicate whether the increase in flow rate will cause the property to increase, decrease, or remain the same. In each case, explain your answer. rho cNaoH m^dot NaoH yNaoH n^dot V^dot MW_NaoH

Your boss would like to connect a high temperature and pressure stream of steam (from another unit at the plant site) to a turbine that will be operated adiabatically and will serve as an energy source for a small electric generator. The steam is at T1 = 600 C and P1 = 10 bar. The outlet conditions of the turbine must be T2 = 400 C and P2 = 1 bar. The inlet diameter to the pipe connecting to the...

Part C The pressure, temperature and volume of a system change differently during the process of isothermal expansion. Indicate whether each quantity increases (I), remains constant (C), or decreases (D). Your answers should describe the changes of pressure, temperature, and volume (in that order). Separate your answers with commas (e.g., I,C,D means pressure increases, temperature remains constant, and volume decreases). Part D What is the work W done by the gas as it expands isothermally from V0 to fvV0? Express...

For a non-ideal gas, as the pressure increases at constant temperature, does the Gibbs free energy increase, decrease , or not change? Explain.
A change in the process requires a higher temperature. The temperature of the pipe increases from...
A change in the process requires a higher temperature. The temperature of the pipe increases from T-800 K to T2 900 K. Now, the flux will change because diffusion will be easier at higher temperatures. This will cause the value of D in Fick's First Law to increase. Assume that the activation energy for the diffusion of hydrogen through the pipe is Ed 1.51x104 J/mol. What is the leak rate for the new process? Express your answer to three significant...
