PLEASE HELP THIS IS URGENT Complete the data table using the procedure above and the video provided. To find the distance from the top of the water column to the top of the air column, subtract the height of the water column from the total distance to the top of the air column. Using the equation v = fฦ, determine the wave speed for each trial. Determine an average wave speed by averaging the wave speeds you found for each trial. To calculate the exact value for the speed of sound, use the temperature given at the beginning of the video and the following equation: Vsound = 331 m/s + 0.6(TCelcius) How close was your average speed to the calculation of the actual value for the speed of sound in m/s? Give 2 examples of errors that may have occurred during the lab that could have caused your value to be different than the value that you determined using the equation.

As part of an industrial process, air as an ideal gas at 10 bar, 400k expands at steady state through a valve to a pressure of 4 bar. the mass flow rate of air is 0.5 kg/s. the air then passes through a heat exchanger where it is cooled to a temperature of 295k with negligible change in pressure. the valve can be modeled as a throttling process, and kinetic and potential energy effects can be neglected. (a) for a control volume enclosing the valve and heat exchanger and enough of the local surroundings that the heat transfer occurs at the ambient temperature of 295 k, determine the rate of entropy production, in kw/k. (b) if the expansion valve were replaced by an adiabatic turbine operating isentropically, what would be the entropy production? compare the results of parts (a) and (b) and discuss.
