Mass Flow Rate of Stream in Turbine (Expanders) Solution

STEP 0: Pre-Calculation Summary

Formula Used

Mass Flow Rate = Work Done Rate/Change in Enthalpy
m = W_rate/ΔH
This formula uses 3 Variables

Variables Used

Mass Flow Rate - (Measured in Kilogram per Second) - Mass flow rate is the mass of a substance that passes per unit of time. Its unit is kilogram per second in SI units.
Work Done Rate - (Measured in Joule per Second) - Work Done Rate performed by a system is energy transferred per second by the system to its surroundings.
Change in Enthalpy - (Measured in Joule per Kilogram) - Change in enthalpy is the thermodynamic quantity equivalent to the total difference between the heat content of a system.

STEP 1: Convert Input(s) to Base Unit

Work Done Rate: 250 Joule per Second --> 250 Joule per Second No Conversion Required
Change in Enthalpy: 190 Joule per Kilogram --> 190 Joule per Kilogram No Conversion Required

Working of turbine (expanders)

The expansion of a gas in a nozzle to produce a high-velocity stream is a process that converts internal energy into kinetic energy, which in turn is converted into shaft work when the stream impinges on blades attached to a rotating shaft. Thus a turbine (or expander) consists of alternate sets of nozzles and rotating blades through which vapor or gas flows in a steady-state expansion process. The overall result is the conversion of the internal energy of a high-pressure stream into shaft work. When steam provides the motive force as in most power plants, the device is called a turbine; when it is a high-pressure gas, such as ammonia or ethylene in a chemical plant, the device is usually called an expander.
