1.Show that the head loss in a hydraulic jump formed in a rectangular channel may be expressed as : change in E =(y2 - y1)^3/(4y1*y2) where y1 and y2 are depth of flow before and after jump.
2.Granny viola has been saving money in the Bread and Butter mutual fund for 15 years . She has been a steady depositor over those years and has a pattern of putting $100 into the account every 3 months. If her original investment 15 years ago was $500 and interest in the account has varied as shown, what is the current value of her savings? years interest Earned in the account 1-5 12% compounded quarterly 6-10 16 compounded quarterly 10-15 8 compounded quarterly
One issue is to calculate the "pooled" variance and "pooled" standard deviation. Since we expect that the variances of the improvement scores by both groups could be a bit different, we'd want an overall value that reflects the variance of both gr..
The rigid bar of negligible weight is supported as shown. Find the stress in each rod if the temperature rises DeltaT after a load P is applied. Use the following data: area of steal rod 320mm2, bronze rod 1300mm2, thermal expansion coefficient Al..
Two 1/2 inch rods are spliced together by glueing a 2 inch section of plastic pipe over the rods ends. If a tensile force P = 350 lb is applied to the spliced nylon rod, what is the average chear stress in the glue joint between pipe and the rods?
Determine the the max weight of the block that the system does not fail if the max tension that can be developed in cable DB is 100N and the max compression that can be developed in tower CD is 100N.
(1) a constant wind velocity that is twice the mean wind velocity and operating half the time; and (2) a constant wind velocity that is three times the mean wind velocity operating one-third of the time.
As a highway patrol officer, you are patricipating in a speed trap. A car passes your patrol car which you clock at 55 mph. One and a half minutes later, your partner in another patrol car situated two miles away from you, clocks the same car at 5..
If this rod is to be used again with an initially straight axis, determine the maximum permissible deflection that may be allowed during testing procedures. Young's Modulus = 210 kN/mm2 and Yield stress of the steel= 240 N/mm2.
The solid circular disk of uniform thickness is released from rest on the 60-degree incline. Calculate the angular velocity w of the cylinder and the magnitude v of the velocity of its center C after it has moved 10 ft down the incline.
For a circular concrete column in a building with a diameter of 12" and subjected to an axial load of 200 kips, determine the stress exerted on the x-section of that column. What type of stress would it be?
The soil below the footings consists of a medium grain sand (SP) and water is located at a depth of 5 feet below the ground surface. The preliminary structural plan calls for a 10 foot wide footing located at a depth of 5 feet which must support a..
Draw a diagram of the room with all of the important parameters noted with symboles. Write a material balance to describe the rate of change in the amount of benzene in the air of the room starting from the time the bottle was opened onwards.
Given below are the measured stream flows in cfs from a storm of 6-hour duration on a stream having a drainage area of 185 mi^2. Derive the unit hydrogaph by the inverse procedure. Assume a constant base flow of 550cfs.
