Homework Answers
The hydraulic diameter is a commonly used term when handling
flow in non-circular tubes and channels. Using this term, one can
calculate many things in the same way as for a round tube.
creeping flow or creeping motion, is a type of fluid flow where advective inertial forces are small compared with viscous forces. The Reynolds number is low.
main difference is Reynolds number. Reynolds number is very low for creeping flow.

shown in the figure below, a hydraulic system has two pistons of different diameter and uses a liquid of density p 850 kg/m3. The smaller piston has a diameter of 4.3 cm anda mass of 1.6 kg and the larger piston a diameter of 14 cm and a mass of 2.7 kg. Determine h the height difference between the two pistons As

Your friend has invented a random number generating machine that returns a value of 1, 2, 3, or 4 when a button is pressed, and you have been asked to test whether the machine displays each number 25% of the time. You generate 100 numbers and observe that 1, 2, and 3 appeared 24 times each and that 4 appeared 28 times. You decide to perform a test of mean of the random variable X, where X = 1 if...

Why has the current account balance of the United States almost always been negative in the last several decades? In other words, what section of the current account is causing the negative cash flow? (2 pts.) What is the major source of capital inflows that allow the negative current account balance to continue? Why does this inflow happen? (2 pts.) Be sure to answer all questions.
