Question

how many fans does it take to lift 150 kg weight​

Answer 1

Answer:

Explanation:

Power can be calculated when you know how fast and how far you need to lift the 150kg load. In other words you need to decide the speed at which you want to lift the load, and then you can calculate Power→

P=Force*velocity

Force= Weight = Mass * Acceleration due to gravity.

g is approximately 10 m/s^2 ~ 9.81 m/s^2

>> P = 150kg*10m/s^2 * velocity

Lets say you want to lift it at 2 meters/second,

P=F*V

P= 1500N * 2m/s

P= 3000W = 3kW
