CASE The mass on Ms. Câs left kidney is hypoattenuating and nonenhancing on CT. It meets Bosniak criteria for a benign simple cyst (class I) and requires no further evaluation or follow-up. Colonoscopy detects multiple colonic polyps that are removed, and the patient does well.
Water pipelines and distribution systems are subjected to surges almost daily, which. over time can cause damage to equipment and possible contamination. Surges are caused by. sudden changes in fluid velocity and can be as minor as a few psi to five times the static. pressure. The causes and effects of these surges in pumping systems will be discussed along. with equipment designed to prevent and dissipate surges. Only with the knowledge of all of the.
Normal Pressure Range. The normal range of water pressure in a residential application is between 40 psi and 80 psi. There is no specific rule about how much pressure is best for your house, since everyone's needs are different.However, anything below 40 psi will likely lead to poor performance of devices that use water.Anything higher than 80 psi could lead to damage, such as blown sprinkler heads or ruptured pipes.his device regulates how much pressure water is allowed to enter a home with. The regulator sits along the main water line, usually in an access panel, crawl space or basement. The regulator has a gauge on the top of the valve that points to how much pressure is coming through the pipe.
