Equations - Meaning and Units

Question 1

equation/units for mass flow rate

Answer 1

ρvA = C
(kg/s)

(A/v can be derived from either end as long as both the same)

Question 2

equation/units for volumetric flow rate

Answer 2

vA = C
(m³/s)

Question 3

equation for volumetric flow rate if mass flow rate already calculated

Answer 3

mass fw/ρ

Question 4

what are the components of Bernoulli’s for total pressure and what they mean?

Answer 4

P = total pressure

p = static pressure
0.5ρv² = dynamic pressure
gρh = potential pressure (due to change in h)

Question 5

what are the components of Bernoulli’s for total head and what they mean?

Answer 5

H = total head (m)

p/ρg = static head
v²/2g = dynamic head
h = natural height (head)
