Power Solution

STEP 0: Pre-Calculation Summary

Formula Used

Power Generated = Force on Fluid Element*Change in Velocity
P_w = F_e*Δv
This formula uses 3 Variables

Variables Used

Power Generated - (Measured in Watt) - Power Generated is the amount of energy liberated per second in a device.
Force on Fluid Element - (Measured in Newton) - Force on Fluid Element is the sum of pressure and shear forces acting on it within a fluid system.
Change in Velocity - (Measured in Meter per Second) - Change in Velocity is the change in speed, or a change in direction, or a change in both speed and direction of an object.

STEP 1: Convert Input(s) to Base Unit

Force on Fluid Element: 2.5 Newton --> 2.5 Newton No Conversion Required
Change in Velocity: 360 Meter per Second --> 360 Meter per Second No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

P_w = F_e*Δv --> 2.5*360

Evaluating ... ...

P_w = 900

STEP 3: Convert Result to Output's Unit

900 Watt --> No Conversion Required

FINAL ANSWER

900 Watt <-- Power Generated
