Normal blood pressure in adults is less than 120/80 mmHg. Low blood pressure is a reading below 90/60 mmHg. Most forms of hypotension happen because your body can’t bring blood pressure back to normal or can’t do it fast enough. For some people, low blood pressure is normal. What isRead More →

Caffeine alone induced a significant increase in blood pressure associated with a decrease in heart rate, whereas nicotine alone increased both blood pressure and heart rate. The combination of caffeine and nicotine increased systolic and diastolic blood pressure by 10.8 +/- 2.0 and 12.4 +/- 1.9 mm Hg, respectively. AreRead More →

Generating higher water pressure from your garden hose allows it to power away muck from automobiles and mold from house siding. Although you can increase the garden hose’s water pressure by adding a high-pressure nozzle, it won’t create the high level of water pressure generated by a pressure washer. HowRead More →

These systems slowly pump hot water through your hot water pipes and back to the water heater through either a dedicated line or through theRead More →

A manometer is a good example, as it uses the surface area and weight of a column of liquid to both measure and indicate pressure. Likewise, the widely used Bourdon gauge is a mechanical device, which both measures and indicates and is probably the best known type of gauge. WhatRead More →

Pressure Potential Positive pressure inside cells is contained by the cell wall, producing turgor pressure. Pressure potentials are typically around 0.6–0.8 MPa, but can reach as high as 1.5 MPa in a well-watered plant. What is the osmotic pressure of a plasmolysed cell? The extent of plasmo- lysis is thusRead More →

Because the aorta is compliant, as blood is ejected into the aorta, the walls of the aorta expand to accommodate the increase in blood volume. As the aorta expands, the increase in pressure is determined by the compliance of the aorta at that particular range of volumes. Does the aortaRead More →
