Answer:
The given function will return an integer in term of j on each iteration of while loop. However, it is noted that this program has some syntax error. The complete code executed in an online R compiler with explanation is given below
Explanation:
def<-function(j){
k=0;
i=1;
while (i<j**3) #j raise to power 3
{
k<-k+1;#k=k+1
i <- i*2;#i=i*2
print(k);#
}
}
def(6)# if you pass the value 6 to function def(j)
Answer:
While air is compressed in a piston cylinder there are following types of irreversibilities
1.Due to finite temperature difference heat transfer take place between cylinder and surrounding.
2.Due friction force between cylinder and piston .
3.Compression process is so fast due to this ,it leads in the irreversibility of system.
Answer: Isentropic process is the process in fluids which have a constant entropy.
Explanation: The isentropic process is considered as the ideal thermodynamical process and has both adiabatic as well as reversible processes in internal form.This process supports no transfer of heat and no transformation of matter .The entropy of the provided mass also remains unchanged or consistent.These processes are usually carried out on material on the efficient device.
Answer:what are you trying to say
Explanation:
Answer: The rate of heat transfer decreases.
Explanation:
Fin effectiveness is defined as the ratio of heat transfer rate from a finned surface to the heat transfer rate from the same surface if there were no fins. Its value is expected to be greater than 1.
Having effectiveness value of 0.9 which is less than 1 indicates that the heat transfer rate will decrease since a fin effectiveness smaller than 1 shows that the fin acts as insulation (thermal insulation).
