Answer:
The force required to keep the plate in place is 251.36 N
Explanation:
Force = pressure × area
velocity of water = 10 m/s
height of water = v^2/2g = 10^2/2×9.8 = 5.102 m
pressure = height × rho × g = 5.102 × 1000 × 9.8 = 49999.6 N/m^2
diameter = 8 cm = 8/100 = 0.08 m
area = πd^2/4 = 3.142×0.08^2/4 = 5.0272×10^-3 m^2
Force = 49999.6 N/m^2 × 5.0272×10^-3 m^2 = 251.36 N
Answer:
59°C
Explanation:
Given that, Cc = McCp,c = 5000 /3600 × 4178 = 5803.2(W/K)
and Ch = MhCp,h = 10000 / 3600 × 4188 = 11634.3(W/K)
Therefore the minimum and maximum heat capacities are:
Cmin = Cc = 5803.2(W/K)
Cmax = Ch = 11634.3(W/K)
The capacity ratio is:
Cr = Cmin / Cmax = 0.499 = 0.5
The maximum possible heat transfer rate is:
Qmax = Cmin (Th,i - Tc,i) = 5803.2 (80 - 20) = 348192(W)
And the number of transfer units is: NTU = UA / Cmin = 11600 / 5803.2 = 1.99
Given that from the appropriate graph in the handouts we can read = 0.7. So the actual heat transfer rate is: Qact = Qmax = 0.7 × 348192 = 243734.4(W)
Hence, the outlet hot temperature is: Th,o = Th,i - Qact / Ch = 59°C
It is habahi Yw with yuuuuuy I am a little more confused about
Answer:
I think it is process or technology
