A roller-coaster car is traveling at a speed of 23 m/s when it passes through point B. At that point, it enters a concave down c
ircular section of the track that has a radius of curvature of 60 m. After it reaches point B, the car’s speed increases at a rate of 4.75 m/s2. Determine the time it takes for the car to reach point D.

Answer:
1123.6 pounds/ square inch.
Explanation:
Fluid pressure is the ratio of force or weight applied by the fluid per unit area.
i.e Fluid pressure =
The maximum load of the jack is obtained at its maximum capacity = 5000 pounds
Area of the large piston on the jack = 4.45 square inches
Thus,
Fluid pressure =
= 1123.5955
Fluid pressure = 1123.6 pounds/ square inch
Thu, the fluid pressure in the jack at maximum load is 1123.6 pounds/ square inch.
Answer:
,
,
Explanation:
Let suppose that fluid is incompressible and diffuser works at steady state. A diffuser reduces velocity at the expense of pressure, which can be modelled by using the Principle of Mass Conservation:
The following relation are found:
The new relationship is determined by means of linear interpolation:
After some algebraic manipulation, the following for the velocity as a function of position is obtained hereafter:
The acceleration can be calculated by using the following derivative:
The derivative of the velocity in terms of position is:
The expression for acceleration is derived by replacing each variable and simplifying the resultant formula.
