Ethanol 39281

How much power can we get if we pour ethanol on a mini turbine from a height of 1.5 m
Volume Ethanol 0.2m3. How much work does ethanol do? The casting time is 1.9 minutes. The density of ethanol is 789 kg/m2.

Correct answer:

W =  2322.027 J
P =  20.3687 W

Step-by-step explanation:

h=1.5 m V=0.2 m3 t=1.9 min s=1.9 60  s=114 s ρ=789 kg/m3 g=9.81 m/s2  m=ρ V=789 0.2=5789=157.8 kg  W=m g h=157.8 9.81 1.5=2322.027 J
P=W/t=2322.027/114=20.3687 W
