/ An irrigation channel irrigates a farm land, A is 120 (Hectare), for time period T= 20 (hr) to increase the moisture

content of the porous soil in the roots zone from its Permanent

Wilting Point, (wv)P%, to its Saturation Condition, (wv)s%. Its

(wv)P% = 10%, (wv)F% = 30%, G = 1.4 and Gs = 2.8.

Compute:

1 The drained moisture content from saturation condition,

(wv)d% by effect of gravity.

2- The depth of drained water, (dw)d.

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.

Wiy doeres rere okhn a pump whon working betwon the same pressure range?
