The tank pressure is 5.08 kPa and the mass flow rate is 2.6 kg/s.
The given parameters:
- <em>Throat area of the nozzle, </em>
<em> = 10 cm² = 0.001 m²</em> - <em>The exit area of the nozzle, A = 28.96 cm² = 0.002896 m²</em>
- <em>Air pressure at sea level = 101.325 kPa</em>
The ratio of the areas of the converging-diverging nozzle is calculated as follows;
From supersonic isentropic table, at 
, we can determine the following;
The tank pressure is calculated as follows;
Thus, the tank pressure is 5.08 kPa and the mass flow rate is 2.6 kg/s.

In order for a system to be in equilibrium , two conditions must be met. Net force must be 0.
Answer:
Option d is correct.
The magnitude of the resultant force upon the piling = 2930 lbs.
Explanation:
Resultant of a group of forces = vector sum of the forces.
Force 1 = (-1250î) lbs
Force 2 = (2650j) lbs
Resultant = (-1250î + 2650j) lbs
The magnitude of the resultant = √[(-1250)² + (2650)²] = 2930 lbs.
Or in visualization method, the two forces presented form a right angled triangle with the resultant of the two forces.
Hence, using Pythagoras theorem,
F₁² + F₂² = R²
(1250)² + (2650)² = R²
R = √[(1250)² + (2650)²] = 2930 lbs.
Distance= speed * time
So multiply speed and time to get the value of distance
20*9.8 =196 meters
Answer:
Gravity Force
Gravity Force(also known as Weight) The force of gravity is the force with which the earth, moon, or other massively large object attracts another object towards itself. By definition, this is the weight of the object <em><u>your welcome </u></em>
