Answer: ∆p2 = 2* ∆p1
Explanation:
Given that all other factors remain constant. The pressure drop across the pipeline is directly proportional to the length.
i.e ∆p ~ L
Therefore,
∆p2/L2 = ∆p1/L1
Since L2 = 2 * L1
∆p2/2*L1 = ∆p1/L1
Eliminating L1 we have,
∆p2/2 = ∆p1
Multiplying both sides by 2
∆p2 = 2 * ∆p1
Answer:
The answer is B Find a safe place to pull over
To solve the problem it is necessary to apply the concepts related to Chvorinov's Law, which states that
Where,
= Volume cube
= Superficial Area from Cube
= Volume Rectangle
= Superficial Area from Rectangle
Our values are given as (I will try to develop the problem in English units for ease of calculations),
Applying the Chvorinov equation we have to,
The stipulated time for the cube is 14.5 then,
Explanation:
Historical sources believe that Henry Ford first saw parts made from vanadium steel in Europe which were been used on racing cars and luxurious vehicles.
Ford was impressed due to the fact that Vanadium steel unlike normal steel was cheaper and at the same time stronger and lighter if it was used on automobiles.
