The flow energy of 124 l/min of a fluid passing a boundary to a system is 108.5 kj/min. determine the pressure at this point

The pressure at this point is 0.875 mPa

Explanation:

Given that,

Flow energy = 124 L/min

Boundary to system P= 108.5 kJ/min

We need to calculate the pressure at this point

Using formula of pressure

Here,

Where, v = velocity

Put the value into the formula

Hence, The pressure at this point is 0.875 mPa

waves moving from a fast medium to a slow medium will experience a reflection as light travels more slowly than red light. total internal reflection occurs when the critical angle is.

the old price per ounce is c/4.

the new price per ounce is c/3.6.

the ratio of the old price to the new one is

(c/4)/(c/3.6) = (c/c)×(3.6/4) = 0.9 . . = 9/10 . . "nine tenths" in either form
