The boiler in an apartment building uses propane (C3H8) to heat
water that circulates throughout the building as steam. 1.00
m'/s of propane gas at 25°C and 1 atm is combusted with 10%
excess air at 25°C and 1 atm. After all of the propane is
combusted, the product gas contains a 10.0:1 molar ratio of
CO2 to CO and leaves the boiler at 25°C. Heat from the boiler
is transferred to a pure water stream at 50°C and 1.0 bar, which
is converted into saturated steam at 20 bar, with no heat lost to
the surroundings in the process. What mass of water is heated
in this process?

A customer has ordered the airplane but requested that its total weight be reduced by 10 percent for fuel saving purposes. An engineer in the design and analysis department has suggested that the weight saving objective can be accomplished by replacing the current aluminum alloy of the floor beams with another one containing 3 wt% Li and 1 wt% Cu. Is this possible? Answer the question by first determining the weight saving that will take place using the Al-Li alloy.
