1. The inlet section of a vacuum cleaner is a rectangle, 1 in by 5 in. The blower is able to provide suction at 25 cubic feet per minute. (a) What is the average velocity at the inlet, in m/s

The average velocity at the inlet is 3.66 m/s.

Explanation:

Given that,

Width = 1 in

Length = 5 in

Flow rate = 25 feet³/m

We need to calculate the average velocity at the inlet

Using formula of velocity at the inlet

Where, Q = flow rate

A = area

Put the value into the formula

Hence, The average velocity at the inlet is 3.66 m/s.

igneous rocks also form where plates converge. the subducting plate melts as it sinks into the crust of the earth, and the melt rises into the overriding plate forming volcanoes. metamorphic rocks are formed mainly in the lithosphere, wherever there is high pressure and high temperature. -woods
