determine the peak flow at point C using the Rational Method. The time of concentration should be calculated using ASCE Kinematic Wave equation. 1) A storm drain system is shown in the figure below. For the flow conditions indicated, IDF equation 110 tc + 16 Where: i- intensity [in h ; tc-time of concentration [min] 0.94 L0.6 no.6 Where: L=length of overland flow (ft); n= Manning's roughness coefficient (0.016); i= rainfall intensity (mm hr-) and S-average overland flow slope (ft...
Time of concentration Determine the time of concentration (te) for an overland flow length of 200 ft on an area in Colorado Springs, CO, with a Manning's roughness coefficient of 0.10, for a design frequency of 25 years. The rainfall intensity-duration relationship for a 25-year frequency is as given in Table 1. Take the average slope of the area as 0.005 ft/ft. Recall that the time of concentration for inlets is given by: where time of concentration (in seconds) 1-overland...
Please help water resources 2. For the drainage system as shown in figure below, determine the design flow and determine the pipe size for each of the sewer section by rational method. The rainfall intensity (in/hr) is given by the IDF curve in second figure. The design frequency storm is 10-year storm. Flow from each area is shown by an arrow. The flow velocity in each pipe can be calculated by Manning's equation or Hazen-William equation by assuming a full...

2. Consider the mass-spring system shown in the figure below. It can be shown that the motion of the mass is governed by the equation a=-sw^2, where s and a are the position and acceleration of the mass, respectively, and w is a constant (which is referred to as the natural frequency of the system). Derive the equation describing the velocity of the mass in terms of the position. Assume that the velocity of the mass is v(subzero) when s=0...
