Week 4 Flashcards
1
Q
Work out mass flow rate
A
ṁ = ρ A v
ṁ = Q ρ
Q = flow rate
2
Q
If the fluid is incompressible what can we assume
A
That the flow rate Q is constant throughout
3
Q
What is Bernoulli’s equation
A
P + 1/2 ρv^2 + ρgh = constant along stream line (P1 + … = P2 + …)
4
Q
When can Bernoulli’s equation be applied
A
When the flow rate is constant
