Water from a main canal is siphoned to a branch canal over an embankment bymeans wrought iron pipes of 9 cm diameter. The length of pipe up to the summitis 25 m and the total length is 65 m. Water surface elevation in the branch canalis 10 m below that of the main canal(i) How many pipes are needed if the total quantity of water required to be conveyed is 60 litre/sec?(ii) What is the maximum permissible height of the summit above the water level in the main canal so that the water pressure of summit may not fall below 0.2 bar absolute, the barometer reading being 10 m of water?Entry loss may be assumed as one-half
of the velocity head in the pipe and takefriction factor f= 0.0075.

An open feedwater heater operates at steady state with liquid entering at inlet 1 with t? = 40°c and pl = 1 .2 mpa. water vapor att2-200°c and p2 = 1.2 mpa enters at inlet 2. saturated liquid water exits with a pressure of pa 1.2 mpa. neglect heat transfer with the surroundings and all kinetic and potential energy effects, determine the mass flow rate of steam at inlet 2 if the mass flow rate of liquid water at inlet 1 is given as 2 kg/s.

Asteam is contained in a rigid tank with a volume of 1 m3. initially, the pressure and temperature are 7 bar and 500 oc, respectively. the temperature drops due to cooling process. determine: (1) the temperature at which condensation begins in °c, (2) the fraction of the total mass that has condensed when the pressure decreased to 0.5 bar. (3) the volume in m3 occupied by saturated liquid at the final state?
