Note:

To use this calculator, enter:

• Mass (m): The fluid’s mass in kilograms (kg).
• Specific Heat Capacity (c_p): How much energy (kJ) is needed to raise the temperature of 1 kg of the fluid by 1°C.
• Temperature Increase (ΔT): How many degrees Celsius (°C) you need to heat the fluid.
• Time (t): The total heating duration in seconds (s).

After you click "Calculate Heat Transfer Rate", the calculator will show the power required (in kW) to achieve that temperature rise within the specified time. A higher value means the fluid heats more quickly, while a lower value indicates slower heating or less power usage.

This is especially helpful in environmental and energy assessments for batch processes (e.g., hot water tanks, industrial fluid heating) to estimate how much energy is needed to heat a fluid to the desired temperature.

Real-Life Application: For instance, in a solar water heating system, this calculation helps determine the required power to heat a storage tank of water during daylight hours, ensuring that the system provides enough hot water for residential or industrial use while optimizing energy consumption.
