Question 1 of 2) A pully drive system is used to transmit power from a diesel engine to a hydraulic pump. The diameter of the smaller pully is 5 (cm). ine diesel engine produces 9.9 (kW) of mechanical power at speed of 2100 (RPM) in its optimum operating point. ne hydraulic pump needs 110 (N.m) of torque to provide hydraulic gage pressure of 220 (bar) at efficiency of 75%. Calculate the followings: 1) Assuming that the diesel engine is running...

WWVUU moressar Q-1 A power plant operates on a regenerative vapor power cycle with one closed feedwater heater. Steam (water vapor) enters the first turbine stage at 120 bar, 520°C and expands to 10 bar, where some of the steam is extracted and diverted to a closed feedwater heater. Condensate exiting the feedwater heater as saturated liquid at 10 bar (State 7) passes through a trap (valve) into the condenser. The feedwater exits the heater at 120 bar with a...

1. The unit cost of installing a solar power system per km² was $5,000 in 2010 when the construction cost index was 1,850. Construction of a 5 MW power system requires 50 km² of land. Estimate the cost of constructing a solar power system of 20 MW in 2020 given that the construction cost index is 2,450 and the size-factor is 0.75? 2. A company that manufactures general-purpose transducers invested $2 million four years ago in high-yield junk box bonds....

[1] A perfectly competitive aluminum producer is currently producing a quantity where the market price is $0.67 per pound (i.e., 67 cents per pound), average total cost is $0.70, and average variable cost of $0.60 (which corresponds to the minimum point on the average variable cost curve). Would you recommend this firm expand output, contract output, or shut down in the short-run? Provide a graph to illustrate your answer. [2] Suppose the local crawfish market is perfectly competitive, with the...
