Asiphon is a tube that exploits bernoulli's equation to move fluid around obstacles, to a lower elevation. one siphon is 2 cm in diameter and transfers fluid from a large reservoir to a 50 l bucket 2 m below the sur- face ofthe reservoir. the siphon travels upward initially, 20 cm above the reservoir surface, then downward to the bucket. along the tube, there is a pinhole at 10 cm below the reservoir's surface level. determine: (a) how long it takes to fill the bucket. (b) if water leaks out or air is drawn in at the pinhole. (c) if the uppermost bend in the siphon is safe from cavitation.

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.
