Most automatic irrigation valves are diaphragm valves in which the water above the diaphragm must be discharged for the valve to open. In a hydraulic system, the controller and valves are connected via small plastic tubes approximately 4 mm (¼ in) in diameter. The controller opens the tube connected to the valve, allowing that valve to open.
A Murphy drip apparatus [1]. A Murphy drip is a rectal infusion apparatus to administer the medical procedure of proctoclysis, also known as rectoclysis. [2] [3] During the procedure, an end of the Murphy drip is inserted into the rectum and large quantities of liquid are infused into the rectum drop by drop. [4]
Drip irrigation systems distribute water through a network of valves, pipes, tubing, and emitters. Depending on how well designed, installed, maintained, and operated it is, a drip irrigation system can be more efficient than other types of irrigation systems, such as surface irrigation or sprinkler irrigation.
Dr. Parshall's initial focus was on the use of his namesake flume to measure flows in irrigation channels and other surface waters. Over time, however, the Parshall flume has proven to be applicable to a wide variety of open channel flows including: Irrigation channels and ditches; Furrows; Surface waters (swales, creeks, streams, and rivers)
Hydraulic motors usually have a drain connection for the internal leakage, which means that when the power unit is turned off the hydraulic motor in the drive system will move slowly if an external load is acting on it. Thus, for applications such as a crane or winch with suspended load, there is always a need for a brake or a locking device.
Cystometry, also known as flow cystometry, is a clinical diagnostic procedure used to evaluate bladder function. Specifically, it measures contractile force of the bladder when voiding . The resulting chart generated from cystometric analysis is known as a cystometrogram (CMG), which plots intravesical pressure against the volume of fluid in ...
Intermittent catheterization is a medical technique used in conditions where patients need either short-term catheter-based management of the urinary bladder or as a daily habit for life. Intermittent catheterization is considered the "gold standard" for medical bladder emptying.
Dethridge wheel in 1936 – Victoria Australia. The Dethridge wheel is an irrigation tool that was invented in 1910 by John Stewart Dethridge (1865–1926). [1] It works in a similar way to a traditional water wheel and rotates as water passes through its vanes.
