Temperature Rise in Pumps

Computes the temperature rise of fluid passing through a pump using: ΔT = P × (1 − η) / (cp × Q × ρ), where P is brake power, η is pump efficiency, cp is specific heat capacity, Q is volume flow rate, and ρ is fluid density.

Inputs

Brake Power(kW)

Shaft power input to the pump in kilowatts

Pump Efficiency

Pump efficiency as a decimal fraction (0–1) — e.g. 0.75 for 75%

Specific Heat Capacity of Fluid(kJ/kg·°C)

Specific heat capacity of the pumped fluid — water ≈ 4.187 kJ/kg·°C

Volume Flow Through Pump(m³/s)

Volume flow rate through the pump in cubic metres per second

Fluid Density(kg/m³)

Density of the pumped fluid — water ≈ 1000 kg/m³

Results

⚠Specific heat capacity must be greater than zero
