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
