Time and time related variables in engineering

Time is the event progression starting from past to present and then, future statistically. The time-related variable is any particular value in relation to time to assess its changes on a specified (XY) plane.

3) b) The normal depth of flow in a 5.0 m wide rectangular channel shown in Figure 3 below is 1.0 m. The channel is laid at a slope of Im/km and has Manning's n of 0.02. Calculate the discharge and velocity in this channel associated with normal flow conditions. c) At a point downstream of that in part (b) above, there is a weir, Az is 0.5 m in height. If the section properties of the channel remains the same as in part (b), determine yı the depth of flow just before the weir. Assume negligible headloss across the weir and critical flow occurs over the weir. (yı lies between 1.2- 1.3 m) YA AZ Y2 Y2 for Q = const AZ Figure 3- Question 3 (b) and 3 (c)
a water resource engineer is in charge of designing atrapezoidal open channel for flood control. Typically, these types of channels are made ofconcrete. Use Manning’s Equation.Flowrate (Qb), channel slope (S0), bottom width (Bw), channel sidewall angle (θ), actual depth(y), and Manning’s coefficient (n) are tabulated below. State all assumptions. * z is the sidewall ratio: for every 1 unit increase in depth, the top width increases by z on eachside of the channel, or 2z total.A) Given the actual depth, y = 1.25 ft, find the discharge Qa.B) Find the Critical Depth, yc, for the discharge Qa found in (a). For a trapezoid,dA/dy =Bw +2 yz .Is the flow sub- or super-critical?C) Determine the uniform flow normal depth (yn) at Qb = 209 cfs.D) If the slope is increased to 0.001, what roughness coefficient would be needed tomaintain the same discharge Qa? What about for Qb? Would it be the same value?
