- If we were to divide the dynamic pressure by the product of fluid density and acceleration due to gravity, g, the result is called velocity head, which is used in head equations like the one used for pressure head and hydraulic head.
- "' Unsaturated "'conditions occur above the water table where the pressure head is negative ( absolute pressure can never be negative, but gauge pressure can ) and the water that incompletely fills the pores of the aquifer material is under suction.
- Whereas in wind tunnels the driving force is usually sophisticated multiblade propellers with adjustable blade pitch, in water and oil tunnels the fluid is circulated with pumps, effectively using a net pressure head difference to move the fluid rather than imparting momentum on it directly.
- The energy equation used for open channel flow computations is a simplification of the Bernoulli Equation ( See Bernoulli Principle ), which takes into account pressure head, elevation head, and velocity head . ( Note, energy and head are synonymous in Fluid Dynamics.
- In summary "'pressure head "'is a measurement of length, which can be converted to the units of pressure ( force per unit area ), as long as strict attention is paid to the density of the measurement fluid and the local value of g.
- Although the astronomical armillary sphere ( representing the celestial sphere ) existed in China since the 1st century BCE, the mathematician and court astronomer Zhang Heng ( 78 139 CE ) provided it with motive power by using the constant pressure head of an inflow water clock to rotate a waterwheel that acted on a set of gears.
- In the design data sheet of chiller, the pressure drop or pressure difference across cooler and condenser is provided by manufacturer, this press . drop is to be maintained for chiller accurate performance or this is the pressure drop to be considered for calculating pressure head for pumps across chiller ( chilled water / condenser pumps ).
- During June to August, southeasterlies of the coastally trapped Kelvin waves and serve to reduce the ITF flow with a minimum in April of 9 Sv . Another way to think about it is that downwelling on the Indian Ocean side increases sea level and so reduces the normal Pacific-to-Indian pressure head reducing the flow.
- An interesting case would be a very tall apartment building-if they were the last to flush, the water would stand in the downpipe waiting to drain, the pressure head might burst the thinner drainpipe within the building ( but they probably design for that ); and if the apartment at the top was the last to flush, the toilets on the lower floors might get a little backflow.
- I wonder why internal combustion engines use centrifugal pumps for the fuel delivery system . this gives us the headaches of priming the pumps . isnt it possible just to use a "'positive displacement pump "'for fuel delivery since it needs no priming ? why prefering the centrifugal ones . moreover i understand centrifugal pumps do not develop good pressure heads .-- Chiwaye 13 : 48, 4 August 2006 ( UTC ) Chiwaye, 04 / 08 / 06
