Gas flows through the pipe of FIGURE Q14.10. You can’t see into the pipe to know how the inner diameter changes. Rank in order, from largest to smallest, the gas speeds va , vb , and vc at points a, b, and c. Explain.

Short Answer

Expert verified

Velocities are vb > va > vc

Step by step solution

01

Given Information

Gas through pipe is given in the figure as below

02

Explanation

Bernoulli's theorem is implied by the conservation of mass and energy in fluid flow.

This means

P1+12ρv12+ρgh1=P2+12ρv22+ρgh2=Constant

From the given figure, from the level of liquid, we can say that

Pc > Pa > Pb

From the Bernoulli's theorem vb > va > vc.

A 70 kg mountain climber dangling in a crevasse stretches a 50-m-long, 1.0-cm-diameter rope by 8.0 cm. What is Young’s modulus for the rope?

A friend asks you how much pressure is in your car tires. You know that the tire manufacturer recommends 30psi, but it's been a while since you've checked. You can't find a tire gauge in the car, but you do find the owner's manual and a ruler. Fortunately, you've just finished taking physics, so you tell your friend, "I don't know, but I can figure it out." From the owner's manual you find that the car's mass is1500kg. It seems reasonable to assume that each tire supports one-fourth of the weight. With the ruler you find that the tires are 15cm wide and the flattened segment of the tire in contact with the road is 13cm long. What answer-in psi-will you give your friend?

Glycerin is poured into an open U-shaped tube until the height in both sides is 20cm. Ethyl alcohol is then poured into one arm until the height of the alcohol column is 20cm. The two liquids do not mix. What is the difference in height between the top surface of the glycerin and the top surface of the alcohol?
