You are faced with a decision on an investment proposal. Specifically, the estimated additional income from the investment is $125,000 per year; the investment cost is $400,000; and the first year estimated expense of $20,000 and will increase a rate of 5% per year. Assume an 8-year analysis period, no salvage value, and MARR = 15% per year. a. Calculate the PW and FW of this proposal? (15points)

b. What is the ERR ( Ԑ=MARR) of this proposal? (10 points)

c. What is the Simple and Discounted payback? (15 points)

(Upload the picture of your complete solutions including the correct cash flow diagram (5points) and your conclusion.)

Line joining liquid phase with liquid and solid phase mixture is known as: a) liquidus b) solidus c) tie line d) none of the mentioned

Air is to be cooled in the evaporator section of a refrigerator by passing it over a bank of 0.8-cm-outer-diameter and 0.4-m-long tubes inside which the refrigerant is evaporating at -20°c. air approaches the tube bank in the normal direction at 0°c and 1 atm with a mean velocity of 4 m/s. the tubes are arranged in-line with longitudinal and transverse pitches of sl- st 1.5 cm. there are 30 rows in the flow direction with 15 tubes in each row. determine (a) the refrigeration capacity of this system and (b) pressure drop across the tube bank. evaluate the air properties at an assumed mean temperature of -5°c and 1 atm. is this a good assumption?

Afull journal bearing has a journal diameter of 27 mm, with a unilateral tolerance of -0.028 mm. the bushing bore has a diameter of 27.028 mm and a unilateral tolerance of 0.04 mm. the l/d ratio is 0.5. the load is 1.3 kn and the journal runs at 1200 rev/min. if the average viscosity is 50 mpa-s, find the minimum film thickness, the power loss, and the side flow for the minimum clearance assembly.
