Chapter 7: Let's say you dump a gallon of water onto an unsuspected squirrel 10 ft below your bedroom window. 1. How much potential energy (ft-lbr) does the water lose? 2. How fast is the water traveling (ft/s) just before impact? 3. True/False: Energy must be conserved, therefore the kinetic energy of the water before impact must equal the kinetic energy of the cat after impact. If you decide the answer is false, what happens to most of the kinetic energy that the water possessed just before impact?

Question
Chapter 7: Let's say you dump a gallon of water onto an unsuspected squirrel 10 ft below your bedroom window. 1. How much potential energy (ft-lbr) does the water lose? 2. How fast is the water traveling (ft/s) just before impact? 3. True/False: Energy must be conserved, therefore the kinetic energy of the water before impact must equal the kinetic energy of the cat after impact. If you decide the answer is false, what happens to most of the kinetic energy that the water possessed just before impact? Chapter 8: Estimate the specific enthalpy of steam (kJ/kg) at 100°C and 1 atm relative to steam at 350°C and 100 bar. (you can assume ideal gas behavior)
