Electric Motors Speed Calc 对比 Torricelli 的使用情况和统计数据

Electric Motors Power Torque Speed Calculator is a physics/math calculator designed to find electric motor power, torque, or speed quickly and easily. Features: - Instant calculation - Results are copyable to other apps - Formulas are included as references - Supports up to 16 decimal places - Supports various units for each input The speed for an electric motor in SI units can be calculated as n = f x ( 2 / p ) x 60 The torque for an electric motor in SI units can be calculated as T = P x 9.549 / n Where: T = torque (Nm) P = power (watts) n = revolution per minute (rpm) f = frequency of electrical power supply (Hz, cycles/sec, 1/s) p = number of poles The speed for an electric motor is determined by the power supply frequency and the number of poles in the motor winding. The torque is the twisting force and is also the driving force of an electric motor. The power produced by the motor depends on the speed of the motor, which is zero at 0% speed and normally at its peak at 100% speed. On an induction motor, the number of poles determines the speed given the frequency of the power. For example, a 2-pole motor on 60 Hz equals RPM = 60*(2/2)*60 RPM = 3600 rpm a 4 pole motor on 60 Hz equal to RPM = 60*(2/4)*60 RPM = 1800 rpm For 6 poles, 1200 rpm, and so on. As speed decreases, the torque increases, so an 8-pole motor has 4x the torque compared to a 2-pole motor with 1/4 the 8-pole motor speed. *60 Hz is the most common frequency in the US. *50 Hz is the most common frequency outside the US.

Torricelli

Torricelli's Theorem Calculator Based on Torricelli's Law, also known as Torricelli's Theorem, this calculator is a tool in fluid dynamics that relates the speed of fluid flowing out of an opening to the height of the fluid above the opening. Features: • Input parameters such as Tank Height, Tank Radius, Spigot Height, and Spigot Radius. • Simulate water flowing out from the tank in 3D. • Simulate the volume of water remaining over time. • Simulate water pressure over time. • Simulate water speed at the spigot over time. • Simulate water distance over time. • Simulate the farthest water height remaining over time. • Simulate the time needed for the water to flow out until reaching the spigot height. Torricelli's Theorem states that if a tank contains liquid and is open to the atmosphere at its top, and there is an orifice in the tank at a height h below the top of the liquid, then the speed of outflow from the orifice is √2gh, provided the liquid obeys Bernoulli's equation and the top of the liquid can be regarded as motionless. Torricelli's Theorem Formula: v = √2 * g * h where: v : Fluid Speed at the Orifice, in meters per second (m/s) h : Height of the Orifice from the Top, in meters (m) g : The acceleration due to gravity, 9.80665 m/s² Thanks for your support, and do visit nitrio.com for more apps for your iOS devices.
