A.
Compared to the mass flow rate of cooling water, the rate of condensation of steam is invariably smaller |
|
B.
Maintaining vacuum on tube side is more difficult than that on the shell side |
|
C.
Water velocity can be increased conveniently to increase the overall heat transfer co-efficient because of its lower specific volume compared to steam |
|
D.
Condenser can act as a storage unit for condensed steam |
|
A.
In a thin spherical shell under internal pressure, hoop stress is equal to the half of axial stress |
|
B.
Thermoplastic material does not follow Hooke's law of elasticity |
|
C.
Components under longitudinal compression is called 'struts' and the load under which strut fails is called crippling or buckling load |
|
D.
At low temperatures (sub-zero) in pressure vessels, the ductility of metal diminishes and brittle fracture occurs while at high temperature in pressure vessels, embrittlement of material may take plac |
