Answer:
Explanation:
k_max = 26.9 w/mk
k_min = 22.33 w/mk
Explanation:
a) the maximum thermal conductivity is given as
K_MAX = k_m v_m + k_p v_p
where k_m is thermal conductvitiy of metal
k_p is thermal conductvitiy of carbide
v_m = proportion of metal in the cement = 0.15
v_p = proportion of carbide in the cement = 0.85

= 66*0.15 + 20*0.85
k_max = 26.9 w/mk
b) the minimum thermal conductivity is given as

= \frac{20*66}{20*0.15 +66*0.85}
k_min = 22.33 w/mk
Answer:
I got u
Explanation:
this will help because using a electric object would be faster and more efficient than to use a manual thing
Answer:1747.53KJ/kg
Explanation:
Given data
Initial Temprature
Quality
Final pressure
Given tank is rigid therefore specific Volume remains same
now calculating properties at 




Now Specific volume of steam at 






Now 

At 8 MPa and 

Since
therefore final state of steam is superheated at 
at this state
(obtained from steam table)
Therefore heat added
