Water Cooling Formula:
| From: | To: |
The water cooling calculation formula (Q = m·cₚ·ΔT) is used to determine the cooling capacity required for thermal management systems. It calculates the heat transfer rate based on mass flow rate, specific heat capacity, and temperature difference.
The calculator uses the fundamental heat transfer equation:
Where:
Explanation: This equation calculates the rate of heat transfer based on the mass flow of the cooling medium, its thermal properties, and the desired temperature change.
Details: Accurate cooling capacity calculation is essential for designing efficient cooling systems, selecting appropriate cooling equipment, and ensuring proper thermal management in various applications including HVAC, industrial processes, and electronic cooling.
Tips: Enter mass flow rate in kg/s, specific heat capacity in J/kg·K, and temperature difference in Kelvin. All values must be positive numbers greater than zero.
Q1: What is the typical specific heat capacity of water?
A: The specific heat capacity of water is approximately 4186 J/kg·K at standard conditions.
Q2: Can this formula be used for other fluids besides water?
A: Yes, this formula applies to any fluid, but you must use the correct specific heat capacity for that particular fluid.
Q3: Why is temperature difference in Kelvin instead of Celsius?
A: Kelvin and Celsius have the same magnitude for temperature differences, but Kelvin is the SI unit for thermodynamic calculations.
Q4: How do I convert flow rate from L/min to kg/s?
A: Multiply L/min by 0.001 (to get m³/min) then by 1000 (density of water in kg/m³) and divide by 60 (to get kg/s).
Q5: What factors affect cooling capacity in real systems?
A: Real systems are affected by heat exchanger efficiency, fluid properties, flow characteristics, and system pressure drops.
