Answer:
The mass is
Explanation:
From the question we are told that
The initial temperature is
The final temperature is
Generally the maximum heat produced by 1 Liter of natural gas is
So the amount of heat produced by 100 L is
=>
Generally given that the efficiency is
Then actual heat received by the water is
=>
=>
Converting to kcal
=>
Generally the specific heat of water is
Generally the heat received by the water is mathematically represented as
=>
=>
Given,
The initial inside diameter of the pipe, d₁=4.50 cm=0.045 m
The initial speed of the water, v₁=12.5 m/s
The diameter of the pipe at a later position, d₂=6.25 cm=0.065 m
From the continuity equation,
Where A₁ is the area of the cross-section at the initial position, A₂ is the area of the cross-section of the pipe at a later position, and v₂ is the flow rate of the water at the later position.
On substituting the known values,
Thus, the flow rate of the water at the later position is 5.99 m/s
