5. Air enters a compressor operating at steady state with a pressure of 14.7 psia, a temperature of 80 F, and a volumetric flow rate of 18 ft3/s. The air exits the compressor at a pressure of 90 psia. Heat transfer from the compressor to its surrounds occurs at a rate of 9.7 BTU/hr per pound of air flowing. The compressor power input is 90 hp. Neglecting kinetic and potential energy effects, and modeling the air as an ideal gas, determine the exit temperature (F).

Pls pls pls pls ! describe, in your own words, how you found the epicenter of the earthquake.

The second largest public utility in the nation is the sole provider of electricity in 32 counties of southern florida. to meet the monthly demand for electricity in these counties, which is given by the inverse demand function p = 1,200 – 4q, the utility company has set up two electric generating facilities: q1 kilowatts are produced at facility 1, and q2 kilowatts are produced at facility 2 (so q = q1 + q2). the costs of producing electricity at each facility are given by c1(q1) = 8,000 + 6q12 and c2(q2) = 6,000 + 3q22, respectively. determine the profit-maximizing amounts of electricity to produce at the two facilities, the optimal price, and the utility company’s profit
