Answer: 510 m/s
Explanation: specific gravity of steam is 18/29 = 0.620
It is the ratio of the density of steam over density of water
400m3/s of steam =
400m3ms * 0.620 of water
= 248m3/s of water
Total flow rate Q = 248 + 7 = 255m3/s
Using Q = AV
Where A is area and V is velocity
V = Q/A
V = 255/0.5 = 510m/s
The answer is to retain the balance pan clean and to keep chemicals from mixing with other chemicals. Also some chemicals can respond with the metal of the balance pan and cause it to oxidize or corrode. Each time you use the balance pan, use weighing paper or a small dish or beaker to weigh out chemicals.
Yes, No, yes
