Air flows through a Venturi channel of rectangular cross section as shown in figure. The constant width of the channel is 0.06 m and the height at the exit is 0.04 m. a) Determine the flow rate when is drawn up 0.1 m in a small tube attached to the static pressure tap at the throat where the channel height is 0.02 m. b) Determine the channel height h2 at section (2) where, for the same flowrate as in part (a), the water is drawn up 0.05 m. c) Determine the pressure needed at section (1) to produce this flow. (Ideal flow) d) Draw the EL and HGL.

Transcribed Image Text:Air flows through a Venturi channel of rectangular cross section as shown in figure.
The constant width of the channel is 0.06 m and the height at the exit is 0.04 m.
a) Determine the flow rate when is drawn up 0.1 m in a small tube attached to the
static pressure tap at the throat where the channel height is 0.02 m.
b) Determine the channel height h, at section (2) where, for the same flowrate as in
part (a), the water is drawn up 0.05 m.
c) Determine the pressure needed at section (1) to produce this flow. (Ideal flow)
d) Draw the EL and HGL.
