Suppose that you wish to assess the hazard posed by a hydraulic jump in a flooded river. The river channel can be assumed to have a uniform rectangular cross-section and you can safely measure the flow speed and depth downstream of the jump to be ud and hd, respectively. Take the gravitational constant to be g = 9.81 ms -2 where required. (a) (b) (c) (d) Derive an equation to determine the flow depth upstream of the hydraulic jump. Formulate the equation as quadratic in D such that f(D) = 0. Give f(D) in symbolic form, using only the downstream Froude number Frd and the ratio D of upstream depth to downstream depth. f(D) = Help

The traditional "Moody-type" pipe friction correlation in Chap. 6 is of the form 2APD f = pVL (pVD и "D, where D is the pipe diameter, L the pipe length, and e the wall roughness. Note that pipe average velocity V is used on both sides. This form is meant to find Ap when V is known. (a) Suppose that Ap is known, and we wish to find V. Rearrange the above function so that V is isolated on the left-hand side.

Please help me in answering the following practice question. Thank you for your help. Consider several elementary planar irrotational flows arranged in a plane in a cartesian coordinate system (x-y plane) with the unit of length in m (meter). A line source with strength 18 m^2/s is located at point A (0, 1); a line sink with strength of 15 m^2/s is located at point B (3, -2); a line vortex with strength of 9 m^2/s is located at point C (4, 1); and a uniform flow of 10 m/s is at angle 30° with positive x-direction (counter-clockwise). Find the resultant velocity and pressure induced at point D (2, 0) by the uniform stream, line source, line sink & line vortex. Pressure at the infinity at upstream of uniform flow is 1000 Pa.Please list all necessary assumptions.
