Acertain thermometer has a time constant of 15 sec and an initial temperature of 20°c. it is suddenly exposed to a temperature of 100°c. determine the rise time, that is, the time to attain 90 percent of the steady-state value, and the temperature at this time. (25 marks) subjected to a very slow harmonic disturbance having a frequency o thermomet suppose, the thermometer was 0.01 hz. the time constant is still 15 sec. what is the time delay in the response of the and how much does the steady-state amplitude response decrease?

Amass of m 1.5 kg of steam is contained in a closed rigid container. initially the pressure and temperature of the steam are: p 1.5 mpa and t 240°c (superheated state), respectively. then the temperature drops to t2= 100°c as the result of heat transfer to the surroundings. determine: a) quality of the steam at the end of the process, b) heat transfer with the surroundings. for: p1.5 mpa and t 240°c: enthalpy of superheated vapour is 2900 kj/kg, specific volume of superheated vapour is 0. 1483 m/kg, while for t 100°c: enthalpy of saturated liquid water is 419kj/kg, specific volume of saturated liquid water is 0.001043m/kg, enthalpy of saturated vapour is 2676 kj/kg, specific volume of saturated vapour is 1.672 m/kg and pressure is 0.1 mpa.
