what does PFDS needed mean
Calculation of peak discharge (10) B. Tube The rational method is the most common method for estimating peak stormflow discharge from small watersheds. (see pages 151-152, in text). metric-unit version of the equation (p. 151, eq. 6.6). 1. The text gives The older U.S. rational method equation (but still used!) is: "q =Ci A", where q is the peak flow from a given storm (cfs), C is a runoff constant (dimensionless), i is the intensity...

Problem 2: Designing Culverts Under a Bridge on El Rio de las Aguas Torenciales A 100-year stom event is being considered in order to design the culverts under a bridge. Figure 3 shows the storm event that may fall on the rural watershed of area 3.2 Km that drains into El Rio de las Aguas Torenciales. It generates runoff all over the watershed. The runoff flows into the river towards the ast point A (Figure 4) in the watershed where...

Problem 7.2.a) The Philip and Green-Ampt equations provide models for “infiltration capacity” (or “potential infiltration”). What assumptions are used in the development of the Philip and Green-Ampt infiltration capacity models? Clearly explain the difference between actual infiltration rate and infiltration capacity (potential infiltration). Under what specific conditions are the two the same? b) State the condition that for a given rainfall (or snowmelt) event would never generate infiltration excess runoff. This should be written in terms of the rainfall/melt rate...

Question 4 (2+3) The Hoover dam is a huge hydroelectric power plant in the desert close to Las Vegas. It creates power by converting the potential energy of water at a height into electrical energy. The power available for generating electricity is given by: P = pQgh, with p = 997 kg/mthe density of water, Q the flow rate of the water (in m3/s), g the gravitational constant and h = 221 m the height of...

Question 4 (1 point) Your facility already includes multiple TACO TA 0824 pumps, so using the same pump for a new application has many advantages in terms of spares and maintenance costs. The new application has a design flow of 0.05 m3/s and a head of 65 m pumping water at 20C. The application includes 42 m of useful elevation gain with the rest being losses, so the system curve can...

(Use your own words, don't copy and paste) Case Study A 55-year-old man presents to the clinic with complaints of chest pain. He states that for the past 5 months he has noted intermittent substernal chest pressure radiating to the left arm. The pain occurs primarily when exercising vigorously and is relieved with rest. He denies associated shortness of breath, nausea, vomiting, or diaphoresis....
