b. Customers that utilize commutator-type motors
2) The primary voltage is 150 volts
Explanation:
The parameters given are;
Number of primary winding, = 50 turns
Number of secondary winding, = 150 turns
Voltage in secondary winding, = 450 volts
Voltage in primary winding =
The relation between ,
,
and
is as follows;
Which gives;
From which we have;
The primary voltage = 150 volts.
Answer:
Kindly check Explanation section.
Explanation:
NB: please check the attachment for the solution to: the boundary layer thickness, the displacement thickness, the momentum thickness the wall shear stress, the friction coefficient, and the drag coefficient for a flat plate with zero pressure gradient in a laminar flow.
===============================
So,for the solution the second part of the question that asked us to state;
What happens if we add a constant positive pressure gradient?
SOLUTION: Whenever we have dp/dx > 0 that is a positive pressure gradient then, we are going to have what is known as a divergent flow which makes pressure to increase in the direction of flow. The pressure will be minimum around the centre. Also, as the velocity decreases(velocity gradient becomes negative), the area of flow increases.
