2087Which are resistive loads & which one are inductive loads : Refrigerator, Split air conditioner, ceiling fans, well pump, fluoresecent bulbs, T.V, CRT Monitors, Adsl Routers, C.P.U, Printers, Deep Freezers, Speakers, DVD Players, Microwave oven etc. ? Output Power for these Appliances Would be same like this : P = V * A * P.F Or would be changed ? thanks
3971Are Refrigerators & Deep Freezers the Inductive load ? How to calculate the Power Factor & hence the Output Power for them ?

Hi my name is Binyam and I'm a 7th grader at Mayfield Woods Middle school. I decided to research civil engineering as my career and i need to know a few thing about your profession. What is your daily routine? What are some advantages and things you like about your job? What are some disadvantages What is the hardest thing you have done? What education have you gone through to become a civil engineer? How long is your work day? What is your work environment like? What is your salary? What made you want to become an engineer? What tools do you you use? Thank you for answering my questions
Plz if anybody has placement paper of HAL mail me i m Chemical engg my id er.kotnala@gmail.com
What will happen to the protection and metering, if the polarity of a single or two PT/PTs in three phase system is reversed? Please provide reference if any.
MY generator water cooler inlet line height - 11 mtr inlet water line height - 7 mtr water come into the line from overhead tank, O/H tank height - 20 mtr the first tapping in the inlet line is 2" line which down to 4 mtr level plateform., second tapping in inlet water line goes to a pump 6" line installed at 4 mtr level plateform, pump capacity 200m3/hr, head- 30 mtr, hp-40. the outlet of pump of 6" water line connected to a header of 6 mtr long of 6" line, on this header the six tapping are connected, 4 nos. 3" line goes to 11 mtr height water cooler the pressure of the line is 0.15 to 0.25 kg/cm2, 2" and 4" pipe line connected to a cooler at 4 mtrlevel plateform. my question is, at 11 mtr height level the quantity of water and flow is not sufficient for my cooler, the temp. of cooler is rises much more. you are requested to suggest the modification of pipe line/ pump for take more water flow and pressure (desired pressure is 1 kg/cm2)
