We have tested a plant's emissions of particulates and found the following data:
Sample number | Stack velocity, ft/s | Particle concentration, g/m3 |
1 2 3 | 50 60 40 | 0.50 0.30 0.70 |
Each sample represents the average over a 20-min period. What was the average particle concentration in this stack over the whole 60 min of this test?
A.a line B.a queue C.an array D.a stack
A、proceeded
B、linger
C、stack
D、spiral
y calibrated. We have recalibrated it and find that the velocity, in order, should have been 8, 12, 16 and 20m/s.The concentration of the gas flowing in
the stack?
