Water at 150 kPa is contained in a 300 L tank.At this state (state 1), 95% of the volume isoccupied by saturated vapour. Heat istransferred to the water thereby raising itspressure and temperature until state 2 isreached. At a pressure of P2 = 3 MPa a safety valve opens and vapour flows out. The processcontinues, maintaining a 3 MPa internalpressure until 73% of the mass in the tank is avapour, then the valve closes (state 3).Determine the following:
a) Total mass that flowed out, me [kg]
b) Total heat transfer, 1Q3 [J] (state 1 to state 3).
A tank contains 50 gal of a solution of NaCl in water (20% wt). To wash the tank, we supply fresh water at 10 gal/min and drain the tank at the constant rate of 10 gal/min. Determi
Why phenol does not react with sodium carbonate & sodium bicarbonate? Reason: This is because Phenol is less acidic than H 2 CO 3 and hence the reaction doesnt takes place.

Q. Show properties of the Borax? Salts of boric acids are known as borates. As said earlier, hydrated borates occur naturally, e.g., borax, Na 2 B 6 0 11 . 5H 2 0, kernite, Na
