Problem Solving. Solve the following problems completely. 5. Motors from two different manufacturers are being considered for application.Both motors are 50Hp, 460 volts, 3 phase, 60 cycles. Motor A operates at 80%efficiency and motor B operates at 89% efficiency. The expected need for themotor is 15 years. Motor A cost P120, 000.00 and motor B P150, 000.00.Electrical energy cost P8.00 per Kw-Hr and the motors will be operating 8 hoursper day, 250 days a year. Assume taxes and insurance are 3% of first cost. Whichmotor should be purchased?

answer please vv

Yes in their book its in the appendix 1. But you can find the table for R134A anywhere in google. Requirements: REQUEST TO YOU SOLVE ALL PARTS HANDWRITING THANKS FULL WARRANTY SOLUTIONS NEED . NO NEED GENERALIZED ANSWER OK

A 4 stroke four cylinder engine is tested while running at 4000 rpm. The inlet air is at 25ºC and pressure is 750 mm of Hg. The piston displacement for each cylinder is 299cc. The A/F ratio is 15:1 and BSFC is 325 g/kWh. The dynamometer reading shows a power out of 80 hp. Assume the calorific value of the fuel as 43 MJ/kg. Find i) Volumetric Efficiency ii) Brake Thermal Efficiency iii) Total Fuel Consumption iv) Brake Mean effective Pressure

A test carried out on a one-cylinder engine that works based on the Otto cycle, gives the following data: moment of rotation or torque = 950N-m; mean effective pressure = 758kPa; inner diameter = 30cm: stroke = 32cm; spin speed = 320rpm; fuel consumption = 0.003 kg / sec; calorific value of fuel = 42000kJ / kg. Determine: a) The thermal efficiency of the motor; b) mechanical efficiency; c) the fuel limit per hour if it has a price of 18.5 pesos per liter. Its relative density is 0.82

You have been tasked with the evaluation of alternate technologies for baseload power generation for a large urban center. The technologies to be considered are (1) coal fired power, (2) gas fired power, (3) nuclear power, (4) solar thermal power with storage, and (5) hydroelectric power. The criteria for assessment and relative weightings are presented below. Criterion Weighting (%) Capital Cost Generation Capacity Environmental Requirements and Impacts Social Acceptance Reliability 25 20 15 10 30 Review the literature for information relevant to each of the selection criteria for the technologies to be considered. Use a Kepner-Tregoe scorecard to determine the weighted scores for each technology option. Your scorecard should include a brief technical justification for the technology options against each criterion, together with references to the cited sources.

Given the following experimental data collected, what is the approximate torque of this motor at peak efficiency?

A cycle has a qin=350Btu/lbm, and a thermal efficiency of 74%. In this case, the expected heat rejected qout is most likely:     320 Btu/lbm     90 Btu/lbm     350 Btu/lbm     260 Btu/lbm
