## Heat Exchanger Energy Balance
The heat transfer rate is determined by the fluid properties and temperature change.
### Formula
**Q = m_dot cp delta_T**
where m_dot is the mass flow rate, cp is the specific heat capacity, and delta_T is the temperature change of the fluid. This applies to each fluid stream independently; at steady state, the heat lost by the hot stream equals the heat gained by the cold stream (minus losses).

हल किया गया उदाहरण
Water at 2 kg/s cooled from 80 deg C to 50 deg C.
- delta_T = 80 - 50 = 30 deg C
- Q = 2 x 4.18 x 30 = 250.8 kW
- This is the heat that must be transferred to the cooling medium.
