Answer:
t = 59.37 s
Explanation:
Given data:
thermal diffusivity
theraml conductivity = k = 22 W/m.K
h = 300 W/ m^2.K
= 25 degree C = 298 k
= 60 degree C = 333 k
= 75 degree C = 348 L
diameter d = 0.1 m
characteristics length Lc = r/3 = = 0.0166
at Bi = 0.226
Ai = 0.982
-1.187 = - 0.02t
t = 59.37 s
Answer:
5.833
Explanation:
Coefficient of Perfomance (COP) is the ratio of refrigeration effect to power input.
where RE is refrigeration effect and P is power input
Here, the power input is given as 30 kW
We also know that 1 ton cooling is equivalent to 3.5 kW hence for 50 tons, RE=50*3.5=175 kW
Now the

The industrial revolution created many jobs, boosted the economy, but created many issues too. Including but not limited too, child labor, decrease in workplace saftey for the sake of profits, hard hours, and many injuries and deaths (i.e. Triangle Shirtwaist Factory Fire). In the short term, companies used the oppertunity of little workers rights to exploit them for profits, yet in the long term boomed the economy and our exports and America's indepence from buying imports.
It costs 300
Perimeter = 2(L+B)
2(10+5)
2(15) = 30
10 — 1metre
X — 30metres
30metres = 300
Hope that helps :)
In general, bury metal conduits at least 6 inches below the soil surface. You may also run them at a depth of 4 inches under a 4-inch concrete slab. Under your driveway, the conduits must be below a depth of 18 inches, and under a public road or alleyway, they must be buried below 24 inches.
