No se ve la foto :( puedes a ser la pregunta otra ves?
Answer:
The answer is 0.727
Explanation:
lemme know if that's right
#include<stdio.h>
#include<string.h>
int main() {
char str1[100];
char str2[100];
printf("\nEnter the String 1 : ");
gets(str1);
strcpy(str2, str1);
printf("\nCopied String : %s", str2);
return (0);
}
Answer:
h = 23.237 W/m2 K
Explanation:
given data:
flow rate = 1.08*10^6 gm/h = 0.3 kg/s
D = 4.5 cm = 0.045 m
L = 10^4 cm = 100 m
surface temperature = 370 K
Surface heat of vapor = 2190 J/kg.k
From energy conservation principle we have
heat transfer btwn surface and air = heat loss due to flow and temp. drop
where
heat transfer btwn surface and air is due to convection
WHERE
from both above equation we have
putting all value to get heat transefer coefficient
h = 23.237 W/m2 K
