1. Carry out the preliminary design of an instrument that provides a readout of the specific availability of any fluid (liquid or gas) in which it is immersed. Determine the necessary sensors and any calibration procedure required.
2. Plot the specific availability of the air in the tank in Example as a function of air pressure. Assume all the remaining variables are constant.
Example :
Determine the specific available energy in a stationary, rigid tank containing air (an ideal gas) at 20.0°C and 1.500 MPa. Take the local environment (ground state) to be at p0 = 0.101 MPa and T0 = 20.0°C = 293 K.
