1. material with higher thermal conductivity should be used for the inner layer and one with lower thermal conductivity for the outer material with lower thermal conductivity should be used for the inner layer
2. material with lower thermal conductivity should be used for the inner layer and one with higher thermal conductivity for the outer
3. it is immaterial in which sequence the insulating materials are used
4. it is not possible to judge unless numerical values of dimensions are given
material with lower thermal conductivity should be used for the inner layer and one with higher thermal conductivity for the outer

2. Superheated cycle
3. Reheat cycle
4. Regenerative cycle
Regenerative cycle
1. to increase overall heat transfer coefficient water side velocity can be increased if water is at the tube side
2. Condenser can act as a storage unit for condensed steam
3. Rate of condensation of steam is invariably smaller than the mass flow rate of cooling water
4. It is easier to maintain vacuum on the shell side than on the tube side
5.
to increase overall heat transfer coefficient water side velocity can be increased if water is at the tube side
