A certain thermometer using pressure as the thermometric property gives the value of pressure as 1.86 and 6.81 at ice point and steam point respectively. The temperature of ice point and steam point are assigned the number 32 and 212 respectively. Determine the temperature corresponding to p-2.5 if the temperature t is defined in terms of pressure p as t = a ln p + b,

3. A certain thermometer using pressure as the thermometric property gives the value of pressure
as 1.86 and 6.81 at ice point and steam point respectively. The temperature of ice point and
steam point are assigned the number 32 and 212 respectively. Determine the temperature
corresponding to p-2.5 if the temperature t is defined in terms of pressure p as t = a ln p + b,
where a and b are constants.
(73°C)
4. A turbine is supplied with steam at a pressure of 20 bar gauge. After expansion in the turbine,
the steam passes to condenser which is maintained at a vacuum of 250 mm of mercury by
means of pumps. Express the inlet and exhaust steam pressure is N/m? and kPa.
(2101396.2 N/m? or 2101.4 kPa
68024 N/m? or 68 kPa)
5. A vessel of cylindrical shape of 50 cm diameter and 75 cm height, contains 4 kg of gas. The
pressure gauge mounted on the vessel indicate 620 mm of Hg above atmosphere. If the
borometer reading is 760 mm of Hg, calculate the absolute pressure of gas in bar. Also determine
the density and specific volume of the gas.
