Water Flow Temperature Rise Calculator

To calculate water flow temperature rise, you need the initial water temperature, flow rate, and heat input or removal information. Use the specific heat capacity of water (about 1 BTU/°F per pound) to determine the heat added or removed. The formula is ΔT = Q / (m * C), where ΔT is temperature rise, Q is heat, m is mass (flow rate * time), and C is specific heat.

Flow Rate (GPM)	Initial Water Temperature (°F)	Heat Added (BTU/hr)	Final Water Temperature (°F)
5	70	10,000	75
10	60	15,000	75
15	80	-5,000	75
20	70	20,000	90

In this table:

• “Flow Rate (GPM)” represents the flow rate of water in gallons per minute.
• “Initial Water Temperature (°F)” is the starting temperature of the water in degrees Fahrenheit.
• “Heat Added (BTU/hr)” is the amount of heat added or removed from the water per hour, measured in British Thermal Units (BTU).
• “Final Water Temperature (°F)” is the temperature of the water after it has passed through the system.

The calculations for the “Heat Added” column depend on the specific system you are working with. To calculate the heat added, you would need to know the specific heat capacity of water (typically around 1 BTU/°F per pound of water) and the energy input or removal from the system, which can vary based on the type of equipment or process involved.

Keep in mind that this table is a simplified example, and the actual calculations may be more complex depending on the specifics of your system and the fluid properties involved. It’s essential to consult relevant engineering or thermal design resources and consider all relevant parameters for a more accurate analysis.

10. What is the relationship between water flow rate and temperature? The relationship between water flow rate and temperature is that an increase in flow rate typically results in a smaller temperature change, and a decrease in flow rate results in a larger temperature change in a closed system.
11. What is the relationship between temperature and flow rate of water? The relationship between temperature and flow rate of water is that as the flow rate increases, the temperature change (ΔT) decreases, and as the flow rate decreases, the temperature change increases, assuming constant heat input.
