Head is expressed in units of distance such as meters or feet. The force per unit volume on a fluid in a gravitational field is equal to ρg where ρ is the density of the fluid, and g is the gravitational acceleration. On Earth, additional height of fresh water adds a static pressure of about 9.8 kPa per meter (0.098 bar/m) or 0.433 psi per ...
In hydrology, discharge is the volumetric flow rate (volume per time, in units of m 3 /h or ft 3 /h) of a stream. It equals the product of average flow velocity (with dimension of length per time, in m/h or ft/h) and the cross-sectional area (in m 2 or ft 2). [1] It includes any suspended solids (e.g. sediment), dissolved chemicals like CaCO
Hydraulics and other studies [1] An open channel, with a uniform depth. Open-channel hydraulics deals with uniform and non-uniform streams. Illustration of hydraulic and hydrostatic, from the "Table of Hydraulics and Hydrostatics", from Cyclopædia, or an Universal Dictionary of Arts and Sciences, edited by Ephraim Chambers, 1728, Vol. 1
Number of miles to walk a day for weight loss. ... although it’s usually between 8,000 and 10,000 steps a day for people under the age of 60. Matheny says that 10,000 steps is a “nice goal ...
On an average day nearly 303 million US gallons (1,150,000 m 3) of water flow from Big Spring in Missouri at a rate of 469 cubic feet per second (13.3 m 3 /s). Grand Prismatic Spring, Yellowstone National Park, Wyoming. A spring is a natural exit point at which groundwater emerges from an aquifer and flows across the ground surface as surface ...
A marathon is always measured by the same distance: 26.2 miles, but the time it takes to finish depends on your fitness level, training and the course itself.
There are 9 power stations capable of pumping with a total installed capacity of 1344 MW and an average annual production of 2247 GWh. The pumped storage hydropower in Norway is built a bit differently from the rest of the world. They are designed for seasonal pumping. Most of them can also not cycle the water endlessly, but only pump and reuse ...
For context, the volume of an Olympic-size swimming pool is 2,500 m 3 (88,000 cu ft). The average flow rate at the mouth of the Amazon is sufficient to fill more than 83 such pools each second. The estimated global total for all rivers is 1.2 × 10 6 m 3 /s (43 million cu ft/s), [1] of which the Amazon would be approximately 18%.
