The value of the critical Reynolds number for the flow over a flat plate is 5 x10^5. The significance of the value is:
(a) The boundary layer will be turbulent where the Reynolds number is less than this value.
(b) At a position along the plate where the Reynolds number equals this value, transition from laminar to turbulent boundary layer gradually occurs.
(c) If the Reynolds number for the plate based on the length L is greater than this value, then the boundary layer is turbulent over the entire plate.
(d) Transition from laminar to turbulent boundary layer will occur immediately when this value is exceeded.
(e) None of the above represent a reasonable answer!

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.
