For axial flow through a circular tube, the reynolds number for transition to turbulence is approximately 2300 based on the diameter and average velocity. if d = 3.6 cm and the fluid is kerosene at 20°c, find the volume flow rate in m3/h that causes the transition. for kerosene at 20°c, take rho = 804 kg/m3 and μ = 0.00192 kg/m⋅s. take π = (22/7) and round the final answer to two decimal places.

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.
