The grain loader has a capacity of 40 tons of grain per hour, Determine the useful power of the loader

The grain loader has a capacity of 40 tons of grain per hour, Determine the useful power of the loader if the grain is lifted to a height of 6.5 m.

The loader power can be calculated using the formula:
P = A / t, where A is the useful work of the loader, t is the operating time (t = 1 hour = 60 * 60 = 3600 s).
Useful work:
A = Fd * h, where Fd is the acting force (Fd = Ft = m * g, m is the mass of grain, m = 40 t = 40,000 kg, g is the acceleration of gravity (we take g = 10 m / s ^ 2), h is the height to which the load was lifted (h = 6.5 m).
Let’s calculate the power of the loader:
P = A / t = m * g * h / t = 40000 * 10 * 6.5 / 3600 = 722 W.
Answer: The power of the grain loader is 722 watts.
