eng.turbine-nozzle-velocity Calculator
Calculates turbine nozzle exit velocity from isentropic expansion using the steam tables approach and nozzle efficiency. Steam turbine nozzle velocity of 900–1,200 m/s is achievable — the blade speed should be approximately 50% of spouting velocity for maximum efficiency.
Inputs
Inlet Temp C
Thermal state of the substance. Check whether the formula needs Celsius, Fahrenheit, or Kelvin (K = °C + 273.15).
Outlet Temp C
Thermal state of the substance. Check whether the formula needs Celsius, Fahrenheit, or Kelvin (K = °C + 273.15).
Inlet Velocity M S
Speed in a specified direction (m/s). Required for momentum, kinetic energy, and wave calculations.
Results
nozzle exit velocity (m/s)
Sample size or count used in the calculation.
velocity increase
Sample size or count used in the calculation.
enthalpy drop (kJ/kg)
Sample size or count used in the calculation.
v₂ = √(2cp·ΔT + v₁²)
Reference formula or conversion factor shown for context.
nozzle efficiency
Useful output divided by total input, as a percentage. True 100% efficiency is impossible — losses appear as heat. LEDs: 30–50%. Electric motors: 85–97%. Switching supplies: 85–95%.
