Answer:
The ACH is 12/h
Solution:
As per the question:
Area of the space, 
Height of the given space, h = 10 ft
Air flow rate, 
Now, to find the Air Change Rate (ACH):
We calculate the Volume of the given space:

Now, the ACH per min:
= 
Now, ACH per hour:
= 
Answer:
1) a. Customers requiring AC electric power transmission for powering remote devices which may include a subsea transmission system where power is distributed to subsea devices
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:
h= 37.9 m
Explanation:
Given that
SG = 0.8 for fuel so density of fluid will be 800 kg/m³.
We know that SG = 13.6 For Hg so density will be 13600 kg/m³.
Now by balancing the pressure




h= 37.9 m
Answer: Electric current originates from positively charged protons negatively charged electrons of an atom.
Explanation:
The movement of ions (positive or negative) from one point to another is called electric current.
An atom has three sub-atomic particles. These are protons, neutrons and electrons.
Protons are positively charged, neutrons have no charge and electrons are negatively charged. Protons and neutrons reside inside the nucleus of an atom whereas electrons revolve around the nucleus.
So, protons and electrons are responsible for originating electric current form an atom as these are the charged particles.
Thus, we can conclude that electric current originates from positively charged protons negatively charged electrons of an atom.
