| 41. | He first proposed braking of passenger trains as a function of speed ( brakes with two working pressure ).
|
| 42. | The ship was powered by three license-built boilers at a working pressure of that gave her a speed of.
|
| 43. | Santa Clara had six water tube boilers with a combined heating surface of and a working pressure of 300 NHP
|
| 44. | The engines were powered by steam from 19 Yarrow boilers and six cylindrical boilers that had a working pressure of.
|
| 45. | From a working pressure of 575 psi in 1927, by 1929 an experimental boiler was operated at 1, 200 psi.
|
| 46. | She had twelve Kampon Type B ( Ro ) boilers with a working pressure of, although only eight were oil-fired.
|
| 47. | In the 1920s either two or three ( sources vary ) received superheated boilers of 200 lb sq in working pressure.
|
| 48. | To offset the reduced number of boilers, the new ones were fitted with forced draught which increased their working pressure to.
|
| 49. | Simple hydraulic cylinders have a maximum working pressure of about 70 stroke of a hydraulic cylinder is limited by the manufacturing process.
|
| 50. | An external precision gear pump is usually limited to a maximum working pressure of and a maximum speed of 3, 000 rpm.
