Question

V=7,5м/с N=150кВт F=?​

Answer 1

Ответ:

N=F*V, F=150000/7.5= ... H

Answer 2

To calculate the force (F) given the velocity (V) and power (N), you can use the formula for power:

$N = \frac{F \cdot V}{1000}$

Where: N = Power (in kilowatts, kW) F = Force (in Newtons, N) V = Velocity (in meters per second, m/s)

You mentioned that V is 7.5 m/s and N is 150 kW. Now, let's solve for F:

$150 kW = \frac{F \cdot 7.5 m/s}{1000}$

First, we need to convert 150 kW to Watts (W) because 1 kW = 1000 W:

$150 kW = 150,000 W$

Now, let's rearrange the formula to solve for F:

$F = \frac{150,000 W \cdot 1000}{7.5 m/s}$

$F = 20,000,000 N$

So, the force (F) is 20,000,000 Newtons.
