- Q1. Difference between prandtl number and Schmidt number?
- Ans.
Prandtl number and Schmidt number are dimensionless numbers used in fluid mechanics.
Prandtl number represents the ratio of momentum diffusivity to thermal diffusivity in a fluid.
Schmidt number represents the ratio of momentum diffusivity to mass diffusivity in a fluid.
Prandtl number is used to characterize the relative importance of heat transfer and momentum transfer in a fluid.
Schmidt number is used to characterize t...
- Q2. What is rankine cycle?
- Ans.
Rankine cycle is a thermodynamic cycle used in power plants to generate electricity.
It is a cycle that involves the use of steam to generate power.
It consists of four processes: heating, expansion, cooling, and compression.
The cycle is named after William John Macquorn Rankine, a Scottish engineer and physicist.
It is commonly used in power plants that use fossil fuels or nuclear energy.
The efficiency of the cycle can b...
- Q3. What js difference between diesel and Otto cycle?
- Ans.
Diesel cycle is a constant pressure cycle while Otto cycle is a constant volume cycle.
Diesel cycle uses compression ignition while Otto cycle uses spark ignition.
Diesel cycle has a higher compression ratio than Otto cycle.
Diesel cycle is more efficient than Otto cycle due to higher compression ratio.
Otto cycle is used in gasoline engines while Diesel cycle is used in diesel engines.
- Q4. Fourier law and newtons law of cooling?
- Ans.
Fourier law and Newton's law of cooling are both related to heat transfer.
Fourier's law states that the rate of heat transfer through a material is proportional to the temperature gradient across the material.
Newton's law of cooling states that the rate of heat loss of a body is proportional to the difference in temperatures between the body and its surroundings.
Both laws are used in various fields such as engineering,...
