Sea surface temperature (or ocean surface temperature) is the temperature of ocean water close to the surface. The exact meaning of surface varies in the literature and in practice. It is usually between 1 millimetre (0.04 in) and 20 metres (70 ft) below the sea surface. Sea surface temperatures greatly modify air masses in the Earth's ...
An operating temperature is the allowable temperature range of the local ambient environment at which an electrical or mechanical device operates. The device will operate effectively within a specified temperature range which varies based on the device function and application context, and ranges from the minimum operating temperature to the maximum operating temperature (or peak operating ...
Rolls-Royce Marine Spey, a gas turbine developed by Rolls-Royce Holdings in the 1960s for marine propulsion. Marine propulsion is the mechanism or system used to generate thrust to move a watercraft through water. While paddles and sails are still used on some smaller boats, most modern ships are propelled by mechanical systems consisting of an ...
Sea surface temperature (SST), or ocean surface temperature, is the water temperature close to the ocean 's surface. The exact meaning of surface varies according to the measurement method used, but it is between 1 millimetre (0.04 in) and 20 metres (70 ft) below the sea surface. The definition proposed by IPCC for sea surface temperature does ...
The U.S. Navy gives the maximum operating depth of the Los Angeles class as 650 ft (200 m), [16] while Patrick Tyler, in his book Running Critical, suggests a maximum operating depth of 950 ft (290 m). [17] Although Tyler cites the 688-class design committee for this figure, [18] the government has not commented on it.
The selection of ice class is based on the operating area in the Russian Arctic, time of year, ice conditions, operating tactics, and whether the vessel operates under icebreaker escort or independently. In addition, icebreaker classes have additional requirements for minimum shaft power and icebreaking capability. [9]
Maximum operating depth. In underwater diving activities such as saturation diving, technical diving and nitrox diving, the maximum operating depth ( MOD) of a breathing gas is the depth below which the partial pressure of oxygen (pO 2) of the gas mix exceeds an acceptable limit. This limit is based on risk of central nervous system oxygen ...
The maximum hot-spot operating temperature is reached by adding the rated ambient temperature of the machine (often 40 °C), a temperature rise, and a 10 °C hot-spot allowance. Electrical machines are usually designed with an average temperature below the rated hot-spot temperature to allow for acceptable life.
