Homework Statement
Water flows through venturi tube at 0.3 litres/s. Diameter of venturi tube is 32mm to 20mm to 32mm and the water density is 1000kg/m^3.
Homework Equations
a) Assuming head loss is neglible, what is pressure difference between 1 and 2.
b) If pressure head difference between these is 45mm what is head loss.
The Attempt at a Solution
So far I have V2 = P1A1V1/P2A2 = 0.9548 and V1 (Q/A) = 0.3731
delta H 1/2 = H1 - H2 = 1/2g (V2^2-V1^2))
delta H 1/2 = 39.3mm
Where do I go from here, if this is even correct ?
Thanks a lot for your help.
