A coral reef is in danger of being destroyed by a seaside construction project. Which of the following best relates to how an engineer would approach this problem? Engineers would focus their efforts on artificial environments, such as aquariums, and work to develop them in order to preserve endangered species. Engineers would do extensive research on the underwater living environment to see how they could better the situation in a natural way. Engineers would develop a specific product to minimize the problem and create a solution. Engineers would leave this issue to marine biologists since they are the experts in this field.

The free convection heat transfer coefficient on a thin hot vertical plate suspended in still air can be determined from observations of the change in plate temperature with time as it cools. Assuming the plate is isothermal and radiation exchange with its surroundings is negligible, evaluate the convection coefficient at the instant of time when the plate temperature is 225C and the change in plate temperature with time (dT/dt) is -0.022 K/s. The ambient air temperature is 25C and the plate measures 0.30.3with a mass of 3.75 kg and a specific heat of 2770J/kgK.

A commercial refrigerator with refrigerant-134a as the working fluid is used to keep the refrigerated space at 2308C by rejecting its waste heat to cooling water that enters the condenser at 188C at a rate of 0.25 kg/s and leaves at 268C. The refrigerant enters the condenser at 1.2 MPa and 658C and leaves at 428C. The inlet state of the compressor is 60 kPa and 2348C and the compressor is estimated to gain a net heat of 450 W from the surroundings. Determine (a) the quality of the refrigerant at the evaporator inlet, (b) the refrigeration load, (c) the COP of the refrigerator, and (d) the theoretical maximum refrigeration load for the same power input to the compressor.

2.24 Carbon dioxide (CO2) gas in a piston-cylinder assembly undergoes three processes in series that begin and end at the same state (a cycle). Process 1-2: Expansion from state 1 where p1 = 10 bar, V1 = 1 m3, to state 2 where V2 = 4 m3. During the process, pressure and pV1.5 volume are related by = constant. Process 2-3: Constant volume heating to state 3 where p3 = 10 bar. Process 3-1: Constant pressure compression to state 1. Sketch the processes on p V coordinates and evaluate the work for each process, in kJ. What is the net work for the cycle, in kJ?
