Ambient pressure concept of pressure becomes irrelevant, and it is undefined at a gravitational singularity. The SI unit of pressure is the pascal (Pa), which is a very small unit relative to atmospheric pressure on Earth, so kilopascals (kPa) are more commonly used in this context. The ambient atmospheric pressure at sea level is not constant: it varies with the weather, but averages around 100 kPa. In fields such as meteorology and underwater diving, it is common to see ambient pressure expressed in bar or millibar. One bar is 100 kPa or approximately ambient pressure at sea level. Ambient pressure may in
Smart Pascal several differences that clearly separate the dialect from standard Object Pascal: In Object Pascal a property is an exposed value that can either be linked to a class-field or a class-member method. This is the traditional way of exposing a value property, where the consumer of the property is abstracted from the reader and writer logic. The consumer does not know if the property is explicitly linked to a field or a writer method. Smart Pascal has full support for the older paradigm but introduces a technique called "property expressions". It basically allows you to program reader and writer logic
