What could be the cause for your pool whips to stop moving after two hours of filtration when the pressure reads normal on the sand filter?

Clean and empty in ground pool filter, clean and empty filter near pool pump. Be sure all whips are clear of dibris. also do a flush of the system. If this does not help, you will need to have a C02 charge done between the pool line and the pool pump. OR you may need to have your impeller replaced in the pool motor.

What is the normal net filtration pressure?
is the force responsible for moving fluid across capillary walls. It is the difference between net hydrostatic pressure and net osmotic pressure. NFP= Net hydrostatic pressure - net osmotic pressure
Why does blood get filtered by the kidneys?
Blood pressure promotes filtration of blood in the kidneys by, generally, being greater in pressure than blood colloid osmotic pressure and glomerular capsule pressure which produces a net filtration pressure of about 10 mm Hg. Net filtration pressure forces a large volume of fluid into the capsular space. When blood pressure increase or decreases slightly, changes in the diameters of the afferent and efferent arterioles can actually keep net filtration pressure steady to maintain normal glomerular filtration. Constriction of the afferent arteriole decreases blood flow into the glomerulus, which decreases net filtration pressure. Constriction of the efferent arteriole slows outflow of blood and increases net filtration pressure.
What could cause the pressure to rise within 30 minutes in a DE pool filtration system?
This is normal with my DE filter. When I first turn the pump on the pressure starts at about 5 psi. During the next 30-60 minutes, it rises to 15 psi and then stablizes there. So, I use 15 psi as my "starting" pressure and don't backwash until it reaches 20 psi. When was the last time you had the filter broken down and cleaned????
Is it normal to feel pressure down there in early pregnancy?
yes because your baby is moving!! :)
Define glomerular filtration rate Name and describe the pressures which are effective at the glomerulus under normal conditions and result in glomerular filtration?
Glomerular filtration is a passive process in which hydrostatic pressure forces fluids and solutes through a membraneThe glomerular filtration rate (GFR) is directly proportional to the net filtration pressure and is about 125 ml/min (180 L/day).The glomeruli function as filters. High glomerular blood pressure (55 mm Hg) occurs because the glomeruli are fed and drained by arterioles, and the afferent arterioles are larger in diameter than the efferent arterioles.
How is effective filtration pressure calculated?
The Net Filtration Pressure (NFP) at the glomerulus is the difference between the net hydrostatic pressure and the blood colloid osmotic pressure acting across the glomerular capillaries. Under normal circumstances we can summarize this as NFP = NHP - BCOP or NFP = 35mm Hg - 25 mm Hg = 10mm Hg This is the average pressure forcing water and dissolved materials out of the glomerular capillaries and into the capsular spaces.
What would happen if the capsular hydrostatic pressure increased above normal?
Net filtration would decrease. Source Mastering A and P book, chapter 25.
What would happen if the capsular hydrostatic pressure were increased above normal'?
Net filtration would decrease. Source Mastering A and P book, chapter 25.
Are blood cells filtered out of the blood in the renal arterioles?
If the filtration slits of the filtration membrane are normal, then RBCs are not pushed out into the filtrate
Is it normal for the oil gauge to drop down very low at a stop?
It is normal for the pressure to drop. It depends what you mean by "very low". Check the oil level and the condition of the oil and filter. The oil and filter may need changing.
What is normal pump pressure range?
The lower the pressure the less work the filter is doing, 7 to 10 psi is a good pressure. Another tip would be to put your hand by the outlet where the water goes back into the pool if the water pushes your hand away you have good pressure also take a pressure reading at the filter, if you put your hand at the outlet and the water does not push your hand away take a pressure reading, backwash the filter, put your hand at the outlet again if it pushes it away go back to the filter look at the gauge and see what it reads now, and that would be your suggested low pressure for your filter.
