2.Water flows in a circular pipe of diameter D at a depth y (< D). The pipe is laid on a constant slope of So and the Manning coefficient is n. At what depth does the maximum flow rate occur?
3.A closed rigid tank contains 2kg of saturated water vapor initially at temperature of 433K. Heat transfer occurs from the system and the pressure drops to 150kPa. Determine the amount of heat loss by the system.
