A rectangular channel having a width of 8m carries a discharge of 18 m3/s at the normal depth of 2.25m. (a) What should be the minimum width to which the channel can be contracted smoothly without causing any choking of flow assuming that the bed of the channel is level all through. (b) Compute the critical slope of this new section if n = 0.012. (c) How long should this channel be if there is a drop of 4m. at...
Calculate the surface area and volume of a rectangular solid measuring 43mm in length, 12mm in width, and 19mm in height (report your answer in cm square and cm cube). The mass of this block is 8.4g. What is it's density and will it sink or float in water?
The following data will be used : A rectangular channel measuring 2m in width on a horizontal slope conveys 3 m3 /s. Assume a frictionless channel. 1) A sub-critical flow depth (y) of 3.0m is observed for the given flow conditions above. Determine the alternate depth for the same specific energy. Determine the critical flow depth. 2) Assume for this question only that the flow depth that is occurring is the super critical flow depth for the specific energy determined...
QUESTION 2 (10 marks) A rectangular gate of width w = 2m, and length L - Xm, and of uniform thickness so that the centre of mass is located at the centroid, holds back a depth of water at 15°C as shown. The water surface is at the same height as the gate hinge. Find the minimum weight of the gate so that the gate remains closed. 8 = 30° L=4m Water Wm
Subcritical, uniform flow of water occurs in a rectangular, horizontal channel with a width of 5.0 m. The flow has a depth of 2.0 m and a flow rate of 5.0 cu.m/s. The flow encounters a 0.25 m rise in the channel bottom. What is the new normal depth? Is the flow above the rise subcritical, critical or supercritical? Assume frictionless flow
1. A rectangular channel is given with a width of B = 8.20m and an uniform flow depth of y = 13.62 m. The flow velocity is given as V = 8 m/s. a. Calculate the scales for discharge, time and force for a model of the channel at the scale of 1:12. b. Calculate the prototype hydrodynamic force acting on a pile of a bridge located in the channel if the force in the model is measured as F...
Problem # 2 A discharge of 4800 m/s occurs in an approximately rectangular channel with a depth of 10 m and a width of 50 m. The channel slopes at a rate of 1/2000. The bed consists of fine sand (ds- 0.177 mm) and medium sand (ds-0.354 mm). Use the Shields diagram to determine whether these sizes will remain stationary or be transported. Assuming that the width and the slope do not change with the discharge, determine the discharge that...
A rectangular coil of N turns and of length a and width b is rotated at frequency f in a uniform magnetic field of magnitude B, as indicated in the figure. The coil is connected to co-rotating cylinders, against which metal brushes slide to make contact. The emf induced in the coil is given (as a function of time t) by E = 2 pi f Nab Bs in (2 pi ft) = e_0 sin (2 pi ft) This is...
