Reheat Rankine Cycle - Processes with h-s Diagram

Reheat Rankine Cycle – Processes with h-s Diagram

Reheat Rankine Cycle is essentially a modification of simple rankine cycle. In reheat rankine cycle, the following improvements are made to increase the efficiency of rankine cycle. Lowering the condenser pressure Increasing the temperature of steam while entering the turbine Large variation in pressure between boiler and condenser Implementation of reheat and regenerative system in the [...]

Simple Rankine Cycle – Processes with h-s Diagram

Simple Rankine cycle is an ideal vapour cycle. It plays a major role in steam power plants. This cycle is mainly based on the conversion of input heat energy into output power, using turbine. The working fluid at the inlet repeatedly undergoes change of phase and in successive operations, energy is transmitted and output power [...]

Thermodynamic System and its Types

Thermodynamic System and its Types

A thermodynamic system (or simply ‘system’) is a definite macroscopic region or space in the universe, in which one or more thermodynamic processes take place. Everything external to a thermodynamic system is called surroundings. System and surroundings are separated by a definite border called boundary. System, surroundings and boundary constitute the universe. See the image [...]

Gas Laws

Gas Laws

Gas laws are laws that explain the behaviour of an ideal gas. The following are some of the important gas laws: Boyle’s law Charles’ law Amontons’ law Joule’s law of internal energy Regnault’s law Avogadro’s law 1. Boyle’s Law: Boyle’s law states that the volume of a given mass of gas (V) is inversely proportional [...]
