Question An ideal Brayton cycle with regeneration has a pressure ratio of 10. Air enters the compressor at 300 K and the turbine at 1200 K. If the effectiveness of the regenerator is 100 percent, determine the net work output and the thermal efficiency of the cycle. Account for the variation of specific heats with temperature.

The gears A and D are rigidly attached to two horizontal shafts ABC and DEF that are held by frictionless bearings. The bearings are mounted in an infinitely stiff mounting frame as shown on the figure below. 40 mm 100 mm 80 mm 20 N·m 50 mm 220 ta 130 mm M H 100 mm Questions: a. Determine the couple M, that must be applied to shaft DEF to maintain equilibrium. b. Determine the reaction forces and moments in points G and H. Both points can be considered to be clamped to the bottom plate. Determine the torsional stress in shafts ABD and DEF which both have a diameter of 10mm and are made out of structural steel A-36 d. Determine the relative angular distortion (twist angle) between points and F. (The deformation of the gears can be neglected) C.

3- Helium is to be compressed from 120 kPa and 310 K to 700 kPa and 430 K. A heat loss of 20 kJ/kg occurs during the compression process. Neglecting kinetic energy changes, determine the power input required for a mass flow rate of 90 kg/min. 20 kJ/kg P-700 kPa 7,-430K He = 90 kg/min P = 120 kPa T, -310 K

11. You are asked to estimate the market value of Ms Mini's house, which has two floors. The first floor is rectangular, 35 feet wide and 45 feet deep. The area of the second floor is about 70% of that of the first floor. The lot size is 45 feet by 100 feet. The lots in the area sell for $6,000 per front foot. The present construction cost for this type and quality of house is $160 per square foot. A personal inspection of the house reveals the following information: (i) The house needs external painting that will cost $2,000. (ii) The house needs minor roof repair that will cost $1,000. (iii) A recent flooding in the basement has caused a damage of $1,500. (iv) A storm door has to be replaced at a cost of $1,300. (v) Fireplace costs $5,000. (vi) Tthe broadloom of the master bedroom has to be replaced at a cost of $1,800. There is no other observable depreciation. Required: What is the value of Ms Mini's house by the Cost Approach?
