A centrifugal pump is used to pump Vodka (S.G. 0.8) at a rate of 20 gallons per minute to the top of a 30 foot tall tank. The owner wants to use the same pump to pump orange juice (S.G. 1.1). Explain how this change in fluid will affect:
a) the rate of flow,
b) pressure at the pump discharge,
c) the energy required by the pump, and
d) the size of the pump motor. (Neglect differences in viscosity and friction losses).
Suppose that from the past experience a professor knows that the test score of a student taking his final examination is arandom variable with mean 70 and standarddeviation 85
A large concrete channel holds a hydraulic jump in which the subcritical depth of flow is 2.5 m. If 40 percent of the specific energy in the flow is lost through the hydraulic jump, what is the specific discharge in this rectangular channel?
A year after buying her car, Anita has been offered a job in Europe. Her car loan is for $15,000 at a 9% nominal interest rate for 60 months. If she can sell the car for $12,000, how much does she get to keep after paying off the loan

A person who retires at age 62 can receive Social Security benefits of $1537 per month, but by waiting for the full retirement age of 66, the person will receive $2057 per month.
At an angle of α=30°with the vertical, a 5kg sphere is suspended on a string of length .8m with a initial velocity of 1.2m/s, it colides with wedge B. ε=.7 between the .9kg wedge and sphere A.
A steel cylinder initially contains nitrogen gas at 200kPa and 25oC. the cylinder is connected to a suply line containing nitrogen at 800kPa and 25oC. A valve is opened, allowing nitrogen to flow into the cylinder until the pressure reaches 800kPa. T..
A sightseeing tourist submarine is constructed. The portals along the side can be assumed to be essentially flat, vertical and 1 meter in diameter. Assume a specific weight of seawater of 10,000 N/m3.
