WhatsApp: +86 18838072829Here are a couple of lame formulae to support the calculations: where P is power (watt or kilowatt), τ is torque (Nm), ω is the angular velocity (radians per second), and dot represents the scalar product. The calculator accepts angular speed in RPM (rounds per minute) and the conversion to radians per second is a simple.
WhatsApp: +86 18838072829The above equation can be rearranged to compute the torque required to achieve given angular velocity and power. The torque injects power, and it purely depends on instantaneous velocity. Relationship Between Torque and Power. To derive the relation between torque and Power, compare the linear equivalent for any rotatory motion.

WhatsApp: +86 18838072829θ = 180° (or π radians) This is a situation where the force vector points directly into r. Again, shoving toward the axis of rotation isn't going to cause any rotation either and, once again, the mathematics supports this intuition. Since sin (180°) = 0, the value of the torque is once again τ = 0. θ = 90° (or π /2 radians) Here ...
WhatsApp: +86 18838072829At standard conditions, the power in 1 m2 of wind with a speed of 5 m/s is (5)3 = 81 W. The power in the same 1 m2 of area when the wind speed is 10 m/s is 647 W.
