Dry bulb temperature- You take a thermometer and hold it in the room and note the temperature. Its basically the ambient temperature that you see. Wet bulb temperature- Again take same kind of thermometer but this time cover its bulb(shiny part other than glass) by a wet cloth fully. Now note the temperature reading. Conclusion- The rate of evaporation from the wet bandage on the bulb, and the temperature difference between the dry bulb and wet bulb, depends on the humidity of the air.
In computer programming, an application programming interface (API) is a set of routines, protocols, and tools for building software applications.An API expresses a software component in terms of its operations, inputs, outputs, and underlying types.n such languages, the API is still distributed as a library. For example, the Java language libraries include a set of APIs that are provided in the form of the JDK used by the developers to build new Java programs.
While API is the active component of a drug, excipients are the inactive or inert substances present in a drug. An API starting material, usually a defined chemical property purchased in the market place or produced in-house, is used in the production of an API.
