2. Mr. Ahmed owns and operates a small business that provides economic consulting services. During the year he spends $ 55,000 on travel to clients and other expenses, and the computer that he owns depreciates by $ 2,000. If he didn't use the computer, he could sell it and earn yearly interest of $ 100 on the money created through this sale. Mr. Ahmed's total revenue for the year is $ 100,000. Instead of working as a consultant for the year, he could teach economics at a small local college and make a salary of $ 50,000.

A convergentâdivergent nozzle has an exit area to throat area ratio of 4. It is supplied with air from a large reservoir in which the pressure is kept at 500 kPa and it discharges into another large reservoir in which the pressure is kept at 10 kPa. Expansion waves form at the exit edges of the nozzle causing the discharge flow to be directed outward.

(a) Find the angle that the edge of the discharge flow makes to the axis of the nozzle.

Hydraulic systems utilize Pascal's principle by transmitting pressure from one cylinder (called the primary) to another (called the secondary). Since the pressures will be equal, if the surface areas are different then the forces applied to the cylinders' pistons will be different. Suppose in a hydraulic lift, the piston of the primary cylinder has a 2.25-cm diameter and the piston of the secondary cylinder has a 24.5-cm diameter. What force, in newtons. must be exerted on the primary cylinder of this lift to support the weight of a 2200-kg car (a large car) resting on the secondary cylinder?

2.73 A fan within an insulated duct delivers moist air at the duct exit at 358C, 50% relative humidity, and a volumetric flow rate of 0.4 m3 / s. At steady state, the power input to the fan is 1.7 kW. The pressure in the duct is nearly 1 atm throughout. Using the psychrometric chart, determine the temperature, in 8C, and relative humidity at the duct inlet.
