Answer:

$q=4.013\:\:kW\\\\T_1=278.91\:\:^{\circ}C\\\\T_2=275.82\:\:^{\circ}C$

Explanation:

$R_{conv,1}=(h_1\pi D_1L)^{-1}=(50*0.25*2)^{-1}=0.01273\:\:K/W\\\\R_{conv,2}=(h^2*4wL)^{-1}=(4*4*1)^{-1}=0.0625\:\:K/W\\\\R_{cond(2D)}=(Sk)^{-1}=(8.59*150)^{-1}=0.00078\:\:K/W$

So, heat rate can be calculated as follows:

$q=\frac{T_{\infty,1}-T_{\infty,2}}{R_{conv,1}+R_{conv,2}+R_{cond(2D)}} =\frac{330-25}{0.076} =4.013\:\:kW$

Surface temperatures can be calculated as follows:

$T_1=T_{\infty,1}-qR_{conv,1}=330-51.09=278.91\:\:^{\circ}C\\\\T_2=T_{\infty,2}+qR_{conv,2}=25+250.82=275.82\:\:^{\circ}C$

zloy xaker [14]

Answer:

E) Please see below as the answer is self -explanatory.

Explanation:

The pareto chart, is used in quality control, and is a combined type of graph, that uses a line-type curve to denote the cumulative percentages of the different types of defects found in a sample (so the maximum value is 100%)

Also, it features a bar chart, which shows the relative occurrence of the different values (as in a histogram) which allows to find easily which defects are more relevant ones, alerting in this way about unacceptable deviations in the manufacturing process (if we are producing a good under given quality standards, for instance).
