A closed, sealed rigid tank contains 1.17 kg water vapor and 11 kg liquid water at equilibrium at a pressure of 2 bar. Two alarms are fitted to the tank: one sounds if the pressure exceeds 10 bar, the other sounds if the temperature exceeds 200 degrees celsius.
- If heat is added to the tank continuously, which alarm sounds first?
- The tank is heated until the contents are saturated vapor. How much heat has been added?
- Which alarms, if any, are soA clean cast iron pipeline 0.3 m in diameter and 300 m long connects two reservoirs having surface elevations 60 m and 75 m. calculate the flow rate assuming water at 10 C and a square-edged entrance. (Assume the loss coefficient for a square-edged entrance and for the exit into reservoir are 0.5 and 1.0, respectively)unding when the contents are saturated vapor?
