Question

A iron rod has a length of 31.41cm and diameter is 4cm. The rod is attached to one side with steam at 100degree celcius and the other side is attached with an ice piece at 0degree celcius. If the thermal conductivity of the rod is 0.9CGS,how much ice will melt in one minute?(Latent heat of ice is 80cal/gm)​

Answer 1

282.6gm

L=31.41cm

d=4cm r=2cm

teta1=100

teta2=0

K=0.9cgs

t=1*60

m=?

A=2*pie*r*h

A=2*22/7*2*31.41

A=394.5096cmsq

mL/t=KAdeltatea/l

m80/60=0.9*394.5096*100/31.41

m=9*3945096*60*-10/3141*80

m=9*936274*-10/3141

m=8876466*-10/3141

m=2826*-10

m=282.6gm
