Answer:
k_max = 31.82 w/mk
k_min = 17.70 w/mk
Explanation:
a) the maximum thermal conductivity is given as
where k_m is thermal conductvitiy of metal
k_p is thermal conductvitiy of carbide
v_m = proportion of metal in the cement = 0.17
v_p = proportion of carbide in the cement = 0.83
= 66*0.17 + 28*0.83
k_max = 31.82 w/mk
b) the minimum thermal conductivity is given as
= \frac{28+66}{28*0.17 +66*0.83}
k_min = 17.70 w/mk
Answer:
Pressure, P = 3724 Pa
Explanation:
Given that,
Depth of water,
Depth of oil,
The density of water,
The densinty of oil,
We need to find the gauge pressure at the bottom of the cylinder. So, total pressure is equal to :
So, the gauge pressure at the bottom of the cylinder is 3724 Pa.
