(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

The problem asks to find the energy conversion efficiency of a blower-nozzle combination that produces a velocity of 30m/s for air with a density of 1.1kg/mcubed. The nozzle has a diameter of .15m

input power is 1 hp

2. Relevant equations

given the flow rate = (density)(Area)(velocity)

3. The attempt at a solution

I know how to find the efficiency but do not know how to convert flow rate in (kg/s) to Power units in order to use (power out/power in) formula

Thanks for your help!
