If manufacturer’s thrust loss requirement is 3% and engine has mass flow of 20 unit then, determine how much bleed mass flow can be used?

If manufacturer’s thrust loss requirement is 3% and engine has mass flow of 20 unit then, determine how much bleed mass flow can be used? Correct Answer 0.3 unit

Bleed correction factor C can be approximated as 2 when it is not mentioned in the question. Bleed mass flow = Thrust loss*Engine mass flow / C = 0.03*20/2 = 0.3 unit.
