An aircraft air conditioner is to be optimized to achieve minimum first cost. During the day the temperature of air in the ACM is reduced to 800 degrees K from Tmax. The net heat transfer of the ACM is _____kJ. The density of air is 1.29 kg/m3, and its specific heat is 1.005 kJ/(kg*K). The cost of the primary heat exchanger in dollars is 38.5V, where V is the volume in cubic inches and the cost of the ACM in dollars is 125.3A, where A is the area in squared inches.    Using A and V as the variables, set up the objective function and constraint to optimize the first cost. Set it up so that there is one constraint equation.

Question
An aircraft air conditioner is to be optimized to achieve minimum first cost. During the day the temperature of air in the ACM is reduced to 800 degrees K from Tmax. The net heat transfer of the ACM is _____kJ. The density of air is 1.29 kg/m3, and its specific heat is 1.005 kJ/(kg*K). The cost of the primary heat exchanger in dollars is 38.5V, where V is the volume in cubic inches and the cost of the ACM in dollars is 125.3A, where A is the area in squared inches. 
 
Using A and V as the variables, set up the objective function and constraint to optimize the first cost. Set it up so that there is one constraint equation.
