Answer:
Option B (Starter Control Circuit) is the right option.
Explanation:
- This same switching is normally put upon this isolated side of something like the transmission Arduino microcontroller throughout the configuration that is using the ignition just to command the broadcast.
- It uses a secondary relay isolated to regulate electrical current throughout the solenoid starting system.
All other given options are not related to the given instance. So the above option is correct.
Given:
diameter of sphere, d = 6 inches
radius of sphere, r =
= 3 inches
density,
= 493 lbm/ 
S.G = 1.0027
g = 9.8 m/
= 386.22 inch/ 
Solution:
Using the formula for terminal velocity,
=
(1)

where,
V = volume of sphere
= drag coefficient
Now,
Surface area of sphere, A = 
Volume of sphere, V = 
Using the above formulae in eqn (1):
= 
=
= 
Therefore, terminal velcity is given by:
=
inch/sec
Answer:
.
Explanation:
Given that
L= 50 m
Pressure drop = 130 KPa
copper tube is 3/4 standard type K drawn tube.
From standard chart ,the dimension of 3/4 standard type K copper tube given as
Outside diameter=22.22 mm
Inside diameter=18.92 mm
Dynamic viscosity for kerosene

We know that

Where Q is volume flow rate
L is length of tube
is inner diameter of tube
ΔP is pressure drop
μ is dynamic viscosity
Now by putting the values



So flow rate is
.
