Question

what is formula of relative density and thrust​

Answer 1

Answer:

Explanation:

Relative density can be calculated directly by measuring the density of a sample and dividing it by the (known) density of the reference substance.

Thrust (F) = momentum thrust + pressure thrust

F=(Me*Ve-Ma*Va) +(Pe-Pa)*Ae

F=(Ma+Mf) *Ve-Ma*Va+(Pe-Pa) *Ae

F=Ma{(1+f)Ve-Va}+(Pe-Pa) Ae
