Self Test 2 balance) (Unsteady State mass 1 Problem Statement A Vertical tank of diameter D and height H has a narrow crack of width W running vertically from top to bottom. If the tank is initially filled with water and alilowed to drain through the crack under the influence of gravity a) Calculate the output volumetric flow rate at any time t Imagine the crack to be a seties of adiacenr orifices, then, integrate to find the total efflux...
Self Test 2 (Unsteady State mass balance) 1. Problem Statement A Vertical tank of diameter D and height H has a narrow crack of width W running vertically from top to bottom. If the tank is initially filled with water and ailowed to drain through the crack under the influence of gravity; a) Calculate the output volumetric flow rate at any time t Imagine the crack to be a series of adjacent orifices, then, integrate to find the total efflux...
From the Textbook: Problems: 1.1 (1 pt)-what slope would lead to a 1% difference between depth in the vertical plane rather than depth measured perpendicular to the channel bottom? Compare this slope to the observation that a channel slope of S. 0.01 m/m is generally considered quite steep for open channel flow.
In the following situations, is the flow steady or unsteady? Explain why briefly a) Flow in a storm sewer during a large storm. b) Flow in a power canal when the turbines have been producing constant power 2.
What is the definition of hydraulic diameter? Why has this quantity been invented? What is the difference between “creeping” flow around a sphere and other types of flow around a sphere? What observations would allow you to distinguish between the two?

1. Identify five examples of an unsteady flow and explain what features classify them as unsteady 2. The velocity of water flow in the nozzle shown is given by the following expression: V = 26/(1 - 0,57,2 Where V = velocity in feet per second, t = time in seconds, x = distance along the nozzle, and L = length of nozzle 4 ft. When x = 0.5L and t = 3 s, what is the local acceleration...
For flow in a pipe of uniform diameter D the loss in hydraulic head, h, is given by: L u2 D 2 where L is the length of the pipe, u is the average flow velocity, g is the acceleration due to gravity and f is a constant. During reconfiguration of a plant it is estimated that the length of the pipe could be reduced by 15% and its diameter increased by 6%. Calculate the maximum percentage by which The...
Homework problem: For a pump, discuss the difference between b required by the motor) and hydraulic horsepower. What are the formulae for th rake horsepower (the power hese as a function d (H or Hp)? What are the units of this quantity when converted to SI? Which is larger, brake or hydraulic horsepower?
1.can someone explains specifically what is the difference between control flow and logical control flow? 2. what is the purpose of using concurrent flows? Does it share resources?
Question 7 Consider flow in an open channel with slope 1:500 and a Manning's n of 0.030. The channel has a rectangular cross-section with a width of 5 m (a) Uniform flow in this channel has a depth of 1.6 m. What is the flowrate in the channel? (4 marks) (b) Suppose that this uniform flow (at point 1 in the figure below) encounters an obstacle on the channel bed (at point 2). How big would the obstacle need to...
