Definition: This calculator determines the thermal capacity of a heat exchanger based on mass flow rate, specific heat capacity, and temperature difference. Purpose: It helps engineers and technicians calculate the heat transfer rate in heat exchanger systems for design and analysis purposes. 2. How Does the Calculator Work?The calculator uses the formula: \[ Q = \dot{m} \times c \times \Delta T \] Where: \( Q \) — Heat exchanger capacity (Watts) \( \dot{m} \) — Mass flow rate (kg/s) \( c \) — Specific heat capacity (J/kg·K) \( \Delta T \) — Temperature difference (Kelvin) Explanation: The capacity is calculated by multiplying the mass flow rate of the fluid by its specific heat capacity and the temperature difference across the heat exchanger. 3. Importance of Heat Exchanger Capacity CalculationDetails: Accurate capacity calculation ensures proper heat exchanger sizing, energy efficiency, and system performance in HVAC, industrial processes, and power generation systems. 4. Using the CalculatorTips: Enter the mass flow rate in kg/s, specific heat capacity (default 4186 J/kg·K for water), and temperature difference in Kelvin. All values must be > 0. 5.
