The T-s, p-v, h-s diagrams are graphical representations of thermodynamic cycles used in vapor, gas, and refrigeration systems.
T-s diagram shows the relationship between temperature and entropy
p-v diagram shows the relationship between pressure and volume
h-s diagram shows the relationship between enthalpy and entropy
Vapor cycle includes processes like evaporation, compression, and condensation
Gas cycle includes process...
The LMTD equation is used to calculate the temperature difference in heat exchangers.
LMTD stands for Logarithmic Mean Temperature Difference.
It is used to calculate the heat transfer rate in heat exchangers.
The equation is: LMTD = (ΔT1 - ΔT2) / ln(ΔT1 / ΔT2)
ΔT1 and ΔT2 are the temperature differences between the hot and cold fluids at the inlet and outlet.
The LMTD equation assumes that the heat transfer coefficient is ...
The effectiveness equation in heat exchanger determines the efficiency of heat transfer.
The effectiveness equation compares the actual heat transfer rate to the maximum possible heat transfer rate.
It takes into account the inlet and outlet temperatures of both fluids and the heat capacity rates.
The equation is commonly used in designing and optimizing heat exchangers.
An example of the effectiveness equation is Q/Qmax =...
The Venturi orifice equation is used to calculate the flow rate of a fluid through a pipe.
It relates the pressure difference between two points in a pipe to the flow rate of the fluid.
It is commonly used in industries such as oil and gas, chemical, and water treatment.
The equation takes into account the diameter of the pipe, the density of the fluid, and the pressure difference.
It can be used to determine the efficienc...
Cavitations in pump is a phenomenon where air bubbles form in the liquid due to low pressure, causing damage to the pump.
Occurs when the pressure in the pump drops below the vapor pressure of the liquid
Can cause erosion, noise, and vibration in the pump
Can be prevented by ensuring proper suction pressure and avoiding high-speed operation
Examples include water pumps, fuel pumps, and hydraulic pumps

A turbine is a machine that converts the energy of a moving fluid (water, steam, gas) into mechanical energy.
Turbines are commonly used in power plants to generate electricity.
There are different types of turbines such as steam turbines, gas turbines, and hydraulic turbines.
The blades of a turbine are designed to capture the energy of the fluid and rotate the shaft connected to a generator.
Turbines are also used in air...
