Question

SAMUEL CANAVERAL · Answer

rule of thumb is 2.4 for each 1 TR .

chetan sharma · Answer

Q=M X CP X DELTA T

M is mass flow rate [kg/s]

CP Specific Heat kJ/(kg*K]

DELTA T for change in temperature [K]

Mohammad Elias Kako · Answer

Q = m' x Cp x DeltaT

Q = load

Muhammad Arsalan Siddiqui · Answer

Q = m' x Cp x DeltaT

Q = load

m' = mass flow rate or volume flow rate which is 1 l/s = 1kg/s almost in case of water

DeltaT = temp difference between water in and water out temperature Normally keep it 5.5 - 6.5 Deg C

Thats the basic formula but always keep some factor of safety
