Two variables, num_boys and num_girls, hold the number of boys and girls that have registered for an elementary school. the variable budget holds the number of dollars that have been allocated to the school for the school year. write code that prints out the per-student budget (dollar spent per student). if a division by zero error takes place, just print out the word "unavailable".

Two flowing streams of argon gas are adiabatically mixed to form a single flow/stream. one stream is 1.5 kg/s at 400 kpa and 200 c while the second stream is 2kg/s at 500 kpa and 100 ? . it is stated that the exit state of the mixed single flow of argon gas is 150 c and 300 kpa. assuming there is no work output or input during the mixing process, does this process violate either the first or the second law or both? explain and state all your assumptions.

Water at 70°f and streams enter the mixing chamber at the same mass flow rate, determine the temperature and the quality of the exiting stream. 0 psia is heated in a chamber by mixing it with saturated water vapor at 20 psia. if both streams enters the mixing chamber at the same mass flow rate, determine the temperature and the quality of the existing system.

For a gate width of 2 m into the paper, determine the force required to hold the gate abc at its location.
