Fans and Blowjob Flashcards
1
Q
Air Power, AP
A
QγTDH
Q = volume flow rate or discharge or capacity
TDH = total dynamic head
γ = specific weight of fluid, (ρg) or (SGγ if γ is not air)
2
Q
Capacity of Fan, Q
A
A*v
A = cross sectional area of duct
v = velocity of fan
3
Q
Total Head, TDH
A
h_s + h_v
h = [(P2-P1)/γ] + (z2-z1) + [(v2^2-v1^2)/2g) + h_f
4
Q
Static Head, h_s
A
[(P2-P1)/γ]
5
Q
Velocity Head, h_v
A
[(v2^2-v1^2)/2g]
6
Q
Mechanical Efficiency. ƞ_m
A
AP/BP * 100
7
Q

A
ƞ_m (h_s/TDH)
8
Q
Fan Efficiency, ƞ_t
A
(AP/BP) * 100
QP_t(SG/BP) *100
P_t = total pressure expressed in kPa or PSI
