The left side of the mechanical energy equation (Equation 7.8a) has three terms: P/, 1/2v 2 ,

The left side of the mechanical energy equation (Equation 7.8a) has three terms: P/ρ, 1/2∝v², and gz. Show that each of these terms has the dimensions of energy per mass of fluid by

Equation 7.8a

a. Converting each term to units of Btu/lb_m, beginning with pressure in psi, density in lbm/ƒt³, velocity in ƒt/s, and height in ƒt.
b. Converting each term to units of J/kg, beginning with pressure in Pa, density in kg/m³, velocity in m/s, and height in m.
