Turbine Steam-Consumption Calculator v2.4. This free program will calculate the steam consumption for a turbine of known power and efficiency. The required data are the inlet steam pressure and temperature, and the exhaust pressure. The program will determine the specific and actual steam consumption, and the outlet steam enthalpy, entropy, temperature and quality.

Energy consumption calculator. kWh calculator. Energy consumption calculation. The energy E in kilowatt-hours (kWh) per day is equal to the power P in watts (W) times number of usage hours per day t divided by 1000 watts per kilowatt:

Wind energy describes the process by which wind is used to produce electricity. The mechanical power is converted into electricity which acts as a useful source. The wind power formula is given in terms of velocity of wind, area of the blade and air density.

Pavanaskar and Mcmains (2015) provided analytical models for spindle, axes and cutting power Altıntaş et al. (2016) proposed an energy consumption model for feature based milling. Energy models ...

Use this calculator in conjunction with software from the Idaho National Laboratory. The software from Idaho National Laboratory is designed to combine validated wind resource data with wind turbine power curves to calculate average wind speed, estimated annual energy production, and capacity factor. Also included with the software is a program ...

Please remember that this calculator works out the 'minimum' battery bank size for a given power consumption. When using an inverter, the current draw on the battery side can be extremely high, so you may need a battery bank that is larger than the minimum. For example, 1200W drawn at 240V is only 5A, whereas at 12V this current increases to 100A.

The outlet pressure of the turbine will be, P 4 = P 4 +P 4 = 1.0+0.0049 = 1.0049 bar Hence the pressure ratio of the turbine is, r pt = P 3 P 4 = 10.4251 1.0049 = 10.3743 The speciﬁc heats C pc and C pt are functions of the temperature within the compressor and turbine respectively. A reasonable approximation is to use the average of T 1 and ...
