Question

PROBLEM 4:
a. Compute the flow rate of 20 °C air through a 0.35 m square edged orifice plate that is
situated in a 0.80 m i.d. pipe. The pressure drop across the plate is 1250 Pa, and upstream
pressure is 2 atm abs.
b. Determine the absolute pressure downstream after the orifice.

Q = Volume flow rate, μ= find, P= find
E, the velocity of approach factor, can be
calculated with E = 1/sqrt(1-B^4)
E =
1
√1-B4
requires knowledge of the product CE.
The beta ratio is ß = d0/d1
Then, the Reynolds number needs to be calculated:
4Q
Red1
π * d₁ * v
Where, v is the fluid kinematic viscosity
And d1 is the circular pipes diameter.
