Answer:
The rate of flow is 75.4 kg/s.
Explanation:
Given that,
Diameter of pipe = 18.0 cm
Diameter = 9.00 cm
Pressure
Pressure in the smaller pipe
We need to calculate the velocity of longer pipe
Using formula of velocity
Put the value into the formula
....(I)
We need to calculate the velocity of smaller pipe
Using Bernoulli's equation
Put the value into the formula
Put the value of v₂ in the equation (I)
We need to calculate the flow
Using formula of flow rate
Where, Q = flow rate
A = area
v = velocity
Put the value into the formula
We need to calculate the rate of flow
Using formula of rate
Put the value into the formula
Hence, The rate of flow is 75.4 kg/s.
