Water leaves a spigot at a rate of 462 cubic inches per minute. How many cubic feet of water is this per hour? (Round your answer to the nearest whole number.)

16 cubic feet per hour

Step-by-step explanation:

We want to convert from cubic inch per minute to cubic feet per hour,

We can use the standard conversion rate:

1 cubic inch per minute = 0.0347222 cubic feet per hour

=> 462 cubic inch per minute = 462 * 0.0347222 = 16.04 cubic feet per hour

Approximating to whole number, it is 16 cubic feet per hour.

reduce the friction between its moving parts

step-by-step explanation:

in fact, by reducing the friction between the moving parts of the machine, it is possible to reduce the energy wasted due to this friction; therefore, more input energy is converted into useful work, and this will improve the efficiency of the machine.
