Answer:
6.004 Ω
Explanation:
For a Y- connected system given that :
Line voltage,
Line current ,
and specified that are in phase.
Hence the impedance will be pure resistive.
For Y-system
= phase voltage
= 120.08 V
Line current = Phase current
Now,
= 6.004 Ω
Answer:
the required diameter is 0.344 m
Explanation:
given data:
flow is laminar
flow of carbon dioxide Q = 0.005 Kg/s
for flow to be laminar, Reynold's number must be less than 2300 for pipe flow and it is given as
arrange above equation for diameter
\frac{\rho Q D}{\mu A }<2300
dynamic density of carbon dioxide = 1.47× Pa sec
density of carbon dioxide is 1.83 kg/m³
D = 0.344 m
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.
