A cooling plant adopted a two-stage cascade refrigeration system to meet the required cooling load. In both upper and lower cycles, the refrigerant leaves condenser as saturated liquid and enters compressor as saturated vapor. The isentropic efficiency of the upper cycle compressor is 80 %, while the lower cycle compressor is 70% efficient. The pressure limits of the upper and lower cycles are 1 MPa and 0.2 MPa with refrigerant-134a, respectively. Heat rejection from the lower cycle to the upper...

A company operates two plants which manufacture the same item and whose total cost functions are C1=6.4+0.04(q1)^2 and C2=7.9+0.02(q2)^2 where q1 and q2 are the quantities produced by each plant. The company is a monopoly. The total quantity demanded, q=q1+q2, is related to the price, p, by p=40−0.02q How much should each plant produce in order to maximize the company's profit? q1=? q2=?

Consider two countries, A and B, whose respective industries produce goods qA and qB. Total world output of the good is given by Q=qA+qB. There is a world demand given by p=102-Q. Suppose that the cost function for country A is given by CA(qA)=7qA while the cost function in country B is given by CB(qB)=3qB. The production of the good generates greenhouse gas emissions which cause global climate change. Total world emissions are 0.5 per unit of good, such that...
