Answer and Explanation:
There are different characteristics for the material of friction surfaces that are given bellow.
- The coefficient of friction of the material of friction surface should be very high.
- Coefficient of friction throughout the surface should be uniform.
- The material should have impacted by moisture and oil
- Material should have great ability to bear high temperature
- Material should have high resistance and high heat of conductivity
Answer:
Head loss = 28.03 m
Explanation:
According to Bernoulli's theorem for fluids we have
Applying this between the 2 given points we have
Here is the head loss that occurs
Since the pipe is horizantal we have
Applying contunity equation between the 2 sections we get
Since the cross sectional area of the both the sections is same thus the speed
is also same
Using this information in the above equation of head loss we obtain
Applying values we get
Answer:
A machine consumes energy whereas an engine produces energy. Engine converts heat energy to Mechanical Energy but machine converts all forms of energy to mechanical energy except heat energy. A engine runs a machine,without a engine a machine can't run.
