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:
(a) water height =408.66 in.
(b) mercury height=30.04 in.
Explanation:
Given: P=14.769 psi ( 1 psi= 6894.76 )
we know that
where
h=height.
Given that P=14.769 psi ⇒P= 101828.6 7
(a)
⇒101828.67=
=10.38 m
So water barometer will read 408.66 in. (1 m=39.37 in)
(b)
=13600
So 101828.67=
=0.763 m
So mercury barometer will read 30.04 in.
Given Information:
Inductance = L = 5 mH = 0.005 H
Time = t = 2 seconds
Required Information:
Current at t = 2 seconds = i(t) = ?
Energy at t = 2 seconds = W = ?
Answer:
Current at t = 2 seconds = i(t) = 735.75 A
Energy at t = 2 seconds = W = 1353.32 J
Explanation:
The voltage across an inductor is given as
The current flowing through the inductor is given by
Where L is the inductance and i(0) is the initial current in the inductor which we will assume to be zero since it is not given.
So the current at t = 2 seconds is
The energy stored in the inductor at t = 2 seconds is
