You can measure the peak runoff rate Q using a storm's Unit Hydrograph, the runoff of a storm over time for a location where rainfall collects in land, to the unit input of rainfall. This graph
How to Calculate the Water Inflow Rate = Calculate the Necessary Sump Pump CapacityTypically most of us just buy a 1/4 hp or 1/2 hp sump pump and throw it in the pit and see what happens. But you can guesstimate the rate at which water is flowing into the sump pit by knowing the...
The unit hydrograph may be defined as the direct runoff (outflow) hydrograph resulting fromone unit of effective rainfall, which is uniformly distributed over the basin at a uniform rate during a specified period of time known as unit time or unit duration. How do you make a hydrograph graph?
Urbanization and climate change are contributing to severe flooding globally, damaging infrastructure, disrupting economies, and undermining human well-being. Approaches to make cities more resilient to floods are emerging, notably with the design of flood-resilient structures, but relatively little is kno...
Size of the insect: The larger it is, the longer it takes to break down. Age of the trap: The digestive fluid is recycled after each digestion, and an older trap may secrete a somewhat weaker mix of acid and enzymes. Temperature: The ambient temperature can affect the rate of decompositi...
How to calculate t3/reverse t3 ratio – National Academy of Hypothyroidism This has been a quick discussion of a complex system. Not all aspects of thyroid testing and treatment have been addressed. Hopefully this discussion will help you understand why simply measuring TSH and T4 (a common prac...
The cover of LIFE magazine from Oct. 21, 1957, shows Smithsonian Observatory scientists working at M.I.T. in Cambridge to try to calculate Sputnik's orbit. Dmitri Kessel/Time Life Pictures/Getty Images Space junk got its start in the middle of the twentieth century, at the very beginning ...
Using a ruler, measure the depth of the water in the cans. Calculate the average of measurements by adding them together and dividing by six. Use the table below to figure out how many minutes you should set your system to run per week. ...
It’s time to let your wildflowers loose! Scatter your seed on a windless day so your seeds germinate in the right place. How much seed do you need? Calculate how much seed you need based on the area of your seedbed: The suggested seeding rate for most wildflowers is½ pound of se...
To calculate the slope at each location, a quadratic or biquadratic surface is fitted to the neighborhood cells using the Least Squares Method (LSM). A surface normal is calculated at the cell location from that surface. At the same location, an ellipsoid normal perpendicular to the tangent ...
