Answer:
0.740833917 ton/hr
Explanation:
Given:
Cooling load, 8890.007 Btu/hr = 2.605 kW
Room size = 180 
According to the thumb rule
1 ton of refrigerant = 12000Btu
Hence for 8890.007 Btu/hr,
the mass flow rate of the refrigerant is =8890.007 / 12000
= 0.740833917 ton per hr
Hence, mass flow rate is 0.740833917 ton/hr
Answer:
(C) 29°
Explanation:
ACME THREAD ANGLE : it is the angle measured between the thread axis and thread the thread flanks, with the help of thread angle we calculate the shape of screw thread it is the mean of v thread and square thread the acme thread angle is denoted by β every thread has its own charactersistics which depends on the pitch and diameter of the thread
Answer:
The current at t= 0 sec, is 0 A
The current at t= 0.5 sec, is 2.2 A
The current at t= 1 sec, is 4.4 A
Explanation:
Given that
q(t) = 2.2 t²
We know that:- the change in the charge w.r.t. time is known as current. So,

q(t) = 2.2 t²

I= 4.4 t
1.
t = 0 s :
I = 4.4 x 0 = 0 A
<u>Therefore, the current at t= 0 sec, is 0 A</u>
2 .
t= 0.5 s :
I = 4.4 x 0.5 = 2.2 A
<u>Therefore, the current at t= 0.5 sec, is 2.2 A</u>
3.
t= 1 s
I = 4.4 x 1 =4.4 A
<u>Therefore, the current at t= 1 sec, is 4.4 A</u>
