The basic ambient temperature rating point of most motors is 40°C. A motor rated for 40°C is suitable for installation where the normal surrounding air temperature does not exceed 40°C (104°F). This is the starting point. When the motor operates at full load, it has a certain temperature rise, which adds to the ambient temperature.
Sep 22, 2018· Specific Speed of Pump. The specific speed "Nq" is a parameter derived from a dimensional analysis which allows a comparison of impellers of various pump sizes even when their operating similar Q H range.. The specific speed can be used to classify the optimum impeller design. Specific Speed of pump (Nq) is defined as the speed in RPM at which a geometrically similar impeller .
Wind Turbine Calculator 1. Wind Turbine Calculator 2. Terms. Wind Turbine Site data. In order to understand the value of a wind turbine you need to know what the wind (and air) conditions are at the intended site. This includes: Air Density Data. This is the average air .
The radius is the length of a rotor blade. The wind speed refers to one point in time, not to an average speed. Air density, which is the mass of air per space, depends on air pressure, temperature and humidity. is a good average value at sea level (air density calculator in German: Luftdichte). The efficiency factor tells, which part of ...
