Hi, 

 

I am calculating the heat losses from an open drain tank with dimensions L x D x H 4.75 x 5.5 x 2 m (rectangular). The tank has a 10 mm insulation and is equipped with a 16 KW heating coil.

 

The procedure I am following is:

1- Heat loss by convection from the bulk fluid to the tank wall (natural convection)

2- Heat loss through the tank wall and the insulation (conduction)

3- Heat loss by convection from the insulation surface to the atmosphere (natural convection) 

 

Is there a way to estimate the tank wall temperature? and The outside surface temperature of the insulating material?

 

the bulk fluid temperature inside the tank is 5 C and the outside temperature (environment) is -17 C.

 

Regards,

Sherif

Sherif Morsi,

 

Can you give me the themal conductivity of insulation?
