choose 3 commercially available motors and recommend the max load of each of these
Homework Answers
1 Single phase induction motor
Maximum loading is in the range of 6-7 kw
2 Traction DC motor- mostly used in traction system or in railways with a maximum rating of 1000kw
3 Traction AC motor - in India maximum rating of ac traction motor is used for the rating of 1150 kw

2.14 Two electric motors are available to satisfy a continuous demand of 85 kW. Motor 1 has an initial cost of $5,500 with an operating efficiency of 91%. Motor 2 has an initial cost of $4,000 with an operating efficiency of 89%. Each motor has a life of 10 years with no salvage value. The annual cost of electricity to run the machines is $19.20 per kW of demand plus...

Backgrouund: Material Safety Data Sheets have been prepared for each commercially available chemical compound. There are several sources for MSDS information. In our lab we have hard copies in yellow MSDS binders. We also have the Aldrich Chemical Catalog, the CRC Handbook of Chemistry and Physics, and the Merck Index. Using a search engine, you can also enter the chemical name along with "MSDS." Also, when looking up a particular compound, make sure that you are getting the actual compound...

Could someone help with the following discussion questions: 1. What are three commercially available drugs that are based on natural compounds from plants. That could also be a medication that is chemically derived from a natural compound or compounds that were originally discovered in plants? (name, plant source, and physiological mode of action.) 2. Conduct a small informal survey among your coworkers, friends or family and find how many pharmaceuticals they know about that are based on plant compounds and...

Rg = 50ohm
Max power is transferred when load is complex conjugate of
system resistance
Therefore for Load Impedance,Zl = 50 -
j*(2*pi*2.5*10^3*5*10^-3)
=> 50 - 78.54 j
Resistance in Load,R = 50 ohm
Capacitance in Load,C = 8.106*10^-7 F = 0.8106 micro

2.14 Two electric motors are available to satisfy a continuous demand of 85 kW. Motor I has an initial cost of S5,500 with an operating efficiency of 91%. Motor 2 has an initial cost of $4,000 with an operating efficiency of 89%. Each motor has a life of 10 years with no salvage value. The annual cost of electricity to run the machines is $19.20 per kW of demand plus $0.12 per kWh of energy use. Determine the...

An exercise room has six weight-lifting machines that have no motors and seven treadmills, each equipped with a 2.5-hp (shaft output) motor. The motors operate at an average load factor of 0.7, at which their efficiency is 0.77. During peak evening hours, all 13 pieces of exercising equipment are used continuously, and there are also two people doing light exercises while waiting in line for one piece of the equipment. Assuming the average rate of heat dissipation from people in...
