WHY WE ARE EXPRESSING KW-HR AS UNIT OF
ELECTRICITY.........?WE CAN EXPRESS IN ANOTHER UNIT.....?
Answer Posted / anil bhatia
the energy meter which measure unit is desine to calculate
kwh . ie 1000 X wattes x Hrs (time consumed or used the
power).
where watts is volts X current .
voltage= is applied/given volts,
current=Amper taken by load

how we test a 3 phase motor on single phase supply....? HOW WE RUN A 3 PHASE MOTOR ON SNIGLE PHASE. supply for testing..? how we verify of a 3 phase motors 6 wire & name thame a1/a2/a3..b1/b2/b3 and c1/c2/c3 for connecting star delta starter ........i have only 1 phase supply ? help forum..........
We are preparing another project which involves Waste heat recovery from a 1 MW GE Engine. The Engine in particular gives out flue gas at 487Deg C with a flow rate of 5650 kg/hour and this can be cooled to 180 Deg C. This gives a thermal output of ~ 594 KW that is available for input to VAM via heat exchanger / boiler. Additionally 581 KW will be available from engine jacket water (temperature profile 80/ 80 Deg C and a flow rate of 50m3/hr) Our estimation is that 300 TR of cooling is possible with a suitable VAM machine(s). Please advise what is the most suitable arrangement with maximum TR and min Capital expenditure. plz reply me as early as possible
