Electric Train Velocity

Click For Summary

To calculate the terminal velocity of a simple electric train moving in a coiled copper wire with magnets, one must consider the forces acting on the train, including magnetic forces and resistance. The terminal velocity occurs when the net force on the train is zero, meaning the magnetic force equals the drag force. The discussion emphasizes the importance of understanding the interaction between the magnetic field and the electric current in the wire. Additionally, participants are encouraged to share their own calculations and methodologies to enhance the understanding of the topic. Engaging in collaborative problem-solving can lead to more accurate results and insights.

If have close pipe system with water inside pressurized at P1= 200 000Pa absolute, density 1000kg/m3, wider pipe diameter=2cm, contraction pipe diameter=1.49cm, that is contraction area ratio A1/A2=1.8 a) If water is stationary(pump OFF) and if I drill a hole anywhere at pipe, water will leak out, because pressure(200kPa) inside is higher than atmospheric pressure (101 325Pa). b)If I turn on pump and water start flowing with with v1=10m/s in A1 wider section, from Bernoulli equation I...
