exists and is an alternate of .

when a pump is used to pump a fluid into a vertically arranged pipe , fixed upright; the fluid would reach a certain height at which point the fluid would stop
in a pipe.
this height at which the fluid has stopped propelling upward could be described as
the head of water.
this measure relates to the pump power .
should a pipe system be used which is less than the head height then fluid will be seen to flow out and over the side of pipe.
if the connecting pipe happens to be of longer measurement than the head, and hence when fixed at height is taller than the head height then the fluid will not likely be seen flowing out of pipe .
if a pump is mounted within a basement of work hall, but the resulting pressure is utilised on the ground floor of same building then some pressure will be lost when pumping upwards , and could be described as head loss.

Formula for Heat loss in a pipe?

pips are generally cylindrical in structure of amount of heat loss through pipe is given by the formula. Q= 2 pi k L(T1-T2)/ln(r2/r1). where. k=conductivity of material of which pipe is made. T1= temperature of inside layer pipe. T2=temperature outside layer of pipe. L= length of pipe. r1= in ( Full Answer )

If i had hair loss from a injury to the head will it grow back.?

It is dependent upon why the hair loss occurred. If from scarringfrom a cut or abrasion, the hair follicles may have been damaged orremoved altogether, due to scar tissue formation, and this wouldresult in hair never growing back. But if it is a trauma-inducedalopecia, it is very likely to be tempor ( Full Answer )

After head gasket job and proper timing engine has loss of power?

it seems like the problem is with your engine piston rings not expanding resulting poor compression and loss of power. it reveals an engine problem and complete overhauling is recommended if affordable otherwise only rings can be installed from best mechanic of town.

How do you compute head loss in a channel bend?

A bend coefficient may be used for 1-D gradually varied flow and multiplied by the upstream cross-section averaged velocity head term, such that Headloss = C *a* u 1 2 /(2g) Where C is the bend coefficient which usually ranges between 0.05 - 0.6. The bend coefficient decreases as the radius o ( Full Answer )

What is the formula to find pressure loss in fire fighting pipe lines?

The British fire and rescue services use the following formula for calculating the pressure loss due to friction in firefighting hose:. P f = 9000 f l L 2 / d 5 bar. where. P f is the frictional loss of pressure, in bar f is the friction factor f = 0.005 for 70 mm or 45 mm hose f = 0.0 ( Full Answer )

Brass putter head loss at the end of club can i repiar the club?

What you need to do in this situation is take it to a golf shop or pro shop and ask them to re-glue the shaft. This will be a very cheap process, not costing a lot of money and depending on how busy they are it could be done in less than a day. If you want to do it yourself you will need a blowtorch ( Full Answer )

How do you calculate head loss?

Head loss can be found by manipulating the Bernoulli equation as follows: Ideal fluid : [P 1 /ρg] + Z 1 + [V 1 2 /2g] = [P 2 /ρg] + Z 2 + [V 2 2 /2g] (assuming no energy loss) Where P = pressure at the point ρ = density of the fluid at all points in the f ( Full Answer )

Does the loss of about 100 hairs per day from one's head considered normal hair loss?

as per my trichologist dr rekha yadav loss of 100 hair per day is normal only when you are able to regrow that much but if scalp starts showing gradually and you are not regrowing equal amounts it is abnormal to lose even 30. you can have a daily hair loss of less than 50 hair but if it is there ( Full Answer )

What is major minor losses in a flow through pipe?

Losses due to the local disturbances of the flow in the conduits such as changes in cross section, projecting gaskets, elbows, valves and similar items are called minor losses. In other words, the losses that occur in pipelines due to bends, elbows, joints, valves, etc. are sometimes called minor l ( Full Answer )

What is a pipe?

Would a bad head gasket cause loss of oil?

It could. Check the coolant in the radiator and in the overflow container. If there is a film of oil on top after it has been sitting for a while, then you have a potential head gasket issue.

What is pipe friction loss?

The energy lost through friction as a fluid flows through a pipe. The amount of energy lost is dependent on both the characteristics of the fluid (viscosity, density) and the pipe (roughness, diameter, length) as well as the rate of flow.

Would a blown head gasket cause loss of compression?

It is possible but it depends on where the crack is. If the crack is from the combustion chamber out, such as through a coolant passage it can also suck in coolant/antifreeze and loose compression.
