Answer:
6 m²
Explanation:
application of fluid pressure according to Pascal's principle for the two pistons is given as:
Where P₁ is the pressure at the input and P₂ is the pressure at the output.
But P₁ = F₁ / A₁ and P₂ = F₂ / A₂
Where F₁ and F₂ are the forces applied at the input and output respectively and A₁ and A₂ are the area of the input pipe and output pipe respectively
Since,
But A₁ = 0.2 m², F₁ = 250 N, F₂ = 7500 N. Substituting values to get:
Therefore, the area of the pipe below the load is 6 m²
Answer:
a) hmax = 13334.65 w/m²k
b) t = 0.288 s
c) t = 0.693 s
d) Q = 6032.37 w = 6.032 kw
e) Transmit Heat transfer Rate into the egg is asked so it is heat of poached egg in boiling watch.
Explanation:
Answer:
η=0.568
Explanation:
At inlet condition
temperature = 30 C and pressure P=1 bar
The maximum temperature = 13456 C
Compression ratio r= 12
We know that for process 1-2
Now for process 2-3
So the cut off ratio ρ=1.97
Efficiency of diesel engine
Now put the values
⇒η=0.568
So the efficiency is 56.8%.
