## Marks 2

One side of a wall is maintained at $$400K$$ and the other at $$300K.$$ The rate of heat transfer through the wall is $$1000W$$ and the surrounding t...
The pressure, temperature and velocity of air flowing in a pipe are $$5$$ $$bar,$$ $$500$$ $$K$$ and $$50$$ $$m/s,$$ respectively. The specific heats ...
$$A$$ gas expands in a frictionless piston-cylinder arrangement. The expansion process is very slow, and is resisted by an ambient pressure of $$100kP... A steel billet of$$2000kg$$mass is to be cooled from$$1250K$$to$$450K.$$The heat released during this process is to be used as a ... A heat reservoir at$$900K$$is brought into contact with the ambient at$$300K$$for a short time. During this period$$9000kJ$$of he... ## Marks 5 At a place where the surroundings are at$$1$$bar$${27^ \circ }C,$$a closed rigid thermally insulated tank contains$$2kg$$air at$$2 bar, ...
