so yopu are saying,,,, 5 % rated power can be considered as heat radiated from an diesel engine.
heat rejected by engine (BTU/MIN) = 5% fuel consumption(lt/hr) X spe gravity of diesel X calorific value/3600 X 237.94
is this formula true??
is that i need to consider the FAN loss in BHP...
hello brewnog,
i have got a formula to calculate radiated heat from alternator,
heat rejected by alternator to ambient = (1-efficiency) X ENGINE BHP X 42.5
in this formula i am not able to understand the value "42.5 " stand for ??
why this is considered any guess?
is that above...
mr jobrag. i am dealin with genrator room/canopy ventilation. for that i need to consider the radiated heat from a diesel engine surface. so that i can calculate the total air required for a genrator. i the quantity o heat from other sources like alternator. i just need what quantity of heat is...
Can anybody help me how to calculate the quantity of heat radiated from an diesl engine. any formula based on BHP?
what are the assumptions that i need to make?
what are the factors that i need to consider whilem calculating the heat radiated from an diesel engine
