The three load contacts connected between the three-phase power line and the motor close to connect the motor to the line. The normally open auxiliary contact connected in parallel with the two Start buttons closes to maintain the circuit to M coil when the Start button is released.
Answer:
Explanation:
It is a circuit where there is only one path for the current, from the power supply source through all the elements of the circuit (Receiver, metallic material that allows the circulation of the electric current, Power source), so that no there is neither independence nor distinction in the different places of this.
Answer:
For lower disk : V = e^θrω(0)/h = 0
At the upper disk: V = e^θrω(h)/h = e^θrω
Hence The physical boundary conditions are satisfied
Explanation:
Velocity field ( V ) = e^θrωz/h
Upper disk located at z = h
<u>Determine the dimensions of the velocity field </u>
velocity field is two-dimensional ; V = V( r , z )
applying the no-slip condition
condition : The no-slip condition must be satisfied
For lower disk Vo = 0 when disk is at rest z = 0
∴ V = e^θrω(0)/h = 0
At the upper disk V = e^θrω given that a upper disk it rotates at z = h
∴ V = e^θrω(h)/h = e^θrω
Hence we can conclude that the velocity field satisfies the appropriate physical boundary conditions.
