Answer:The highest possible efficiency of this heat engine is 11%
Explanation:
Saturated water temperature at P1, Pressure in Heat addition,
1.1 MPa=185°C +273= 458K
Saturated water temperature at P2, Pressure in Heat rejection,
0.3MPa=133.5°C+ 273=406.5K
The highest possible efficiency of any heat engine is the Carnot efficiency given as
Carnot efficiency, ηmax = 1- (T2/ T1)
1- (406.5K/458K)
1-0.88755=0.112
=11%
Answer:
First statement: The particles which are displaced is parallel to the direction of energy transport or to the direction the wave travels.
Second statement: amplitude is measured by determining how far the molecules of the medium have been displaced from their normal rest position.
Third statement: wavelength is measured through determining the distance between one point on the wave and the corresponding point on the next one.
Explanation:
Wave can be defined as a displacement that occurs in a medium, from one point to another. There are two different kinds of waves in physics which includes:
- Longitudinal wave and
- Transverse wave.
In a longitudinal wave, particles are displaced parallel to the direction of energy transport or to the direction the wave travels. There are also different properties which can be used to describe a longitudinal wave and they includes:
- amplitude: amplitude is measured by determining how far the molecules of the medium have been displaced from their normal rest position in a longitudinal wave.
- wavelength is measured through determining the distance between one point on the wave and the corresponding point on the next one.
An energy that is related to mass and speed would most likely be kinetic energy.
K= 1/2mv^2
