1. The problem statement, all variables and given/known data Venturi effect nozzle.. Starts off at 100cm and goes down to 40cm. The flow rate of the gas is 2.23 m3/s. What is the average velocity at the beginning and end of the nozzle. 2. Relevant equations Continuity Formula, Bernelli = Q = A1V1=A2V2 3. The attempt at a solution It's not the solution I am having trouble with so much, I am having a brain fart with units. I can take the area of 100cm and get 7850 cm2 and 40cm works out to 1256cm2 and you end up with a starting velocity of 0.000284 and an ending velocity of 0.001775 which I am assuming is cm/s.. Is that right or do I need to convert 100cm and 40cm to meters first and then do the calculation and then end up with meters/s?
