3 cards from this section. Quick, good the night before a test.
What does the coefficient of discharge (Cd) represent?
Think about what adjustments need to be made for real-world applications.
What are the assumptions made when using Bernoulli's equation?
Recall the flow conditions required for Bernoulli's equation to hold.
What is the range of the coefficient of discharge (Cd) in nozzles?
Think about the ideal versus practical scenarios.
Bernoulli's equation is applicable under what conditions?
Recall the ideal conditions for using this equation.
Assume a nozzle with an inlet pressure of 200 kPa. If the outlet area is 0.01 m² and the coefficient of discharge is 0.85, find the actual flow rate in liters per minute.
Convert units as necessary and remember to consider the pressure difference.
How would you modify your calculations if you found that the flow was highly turbulent and the discharge coefficient was only 0.65 instead of 0.85?
Focus on the impact of changes in the discharge coefficient on fluid flow predictions.
