Answer:
Pressure at P point is given as

Explanation:
As we know by poiseuille's equation of viscous flow of liquid through cylindrical pipe

here we know that
L = 4 cm

r = 1 mm
Q = flow rate





now we have



To solve this problem we will apply the concepts related to the kinematic equations of linear motion. We will calculate the initial velocity of the object, and from it, we will calculate the final position. With the considerations made in the statement we will obtain the total height. Initial velocity of the acorn,

Also, it is given that the acorn takes 0.201s to pass the length of the meter stick.

Replacing,


The height of the acorn above the meter stick can be calculated as,




Also the top of the meter stick is 1.87m above the ground hence the height of the acorn above the ground is


Answer:
his is a multi-part question. Once an answer is submitted, you will be unable to return to this part. Air enters a nozzle steadily at 2.21 kg/m3 and 40 m/s and leaves at 0.762 kg/m3 and 192 m/s. The inlet area of the nozzle is 90 cm2.
determine (a) the mass flow rate through the nozzle, and (b) the exit area of the nozzle.
a)0.7956kg/s
b)5.437 × 10⁻³m²
Explanation:
The concepts related to the change of mass flow for both entry and exit is applied
The general formula is defined by

Where,

values are divided by inlet(1) and outlet(2) by


PART A) Applying the flow equation

PART B) For the exit area we need to arrange the equation in function of Area, that is
