41. Minehunters are generally small, fluid pressure generated by the moving hull that may otherwise detonate mines with a hydraulic pressure trigger. 42. In addition, the workcenters and tooling can be large and expensive because of the internal fluid pressures required to form ambient tubes. 43. The lifting injector can operate with negative inlet fluid pressure i . e . fluid lying below the level of the injector. 44. In a disc-brake system, the fluid pressure moves the piston against the back of the brake pad, forcing it against the spinning rotor. 45. The shunt was inserted at the Mayo Clinic this summer to relieve fluid pressure on the brain, a condition called normal pressure hydrocephalus. 46. Automatic Control Valves do not require an external power source, meaning that the fluid pressure is enough to open and close the valve. 47. About 3 million Americans have glaucoma, a disease in which the normal fluid pressure in the eyes slowly rises, possibly leading to blindness. 48. As well as affecting the sediment stress, fluid pressure ( p w ) can affect the friction between the glacier and the bed. 49. The hair cells turn the fluid pressure and other mechanical stimuli into electric stimuli via the many microvilli that make up stereocilia rods. 50. Since a conservative body force is the gradient of some potential function, it has the same effect as a gradient in fluid pressure .
