Consider the mixing of 0.8 kg/s of hot water at 348 K and 1 kg/s of cool water at 298 K that is generating warm water. Assume no work is being done and the system is in steady state, but heat is lost at the rate of 30 kJ/s during this mixing. Find the temperature of the warm water flow stream? Assume Cp = 4.18 kJkg

Write a method dominant that accepts three integers as parameters and returns true if any one of the three integers is larger than the sum of the other two integers. The integers might be passed in any order, so the largest value could be any of the three. If no value is larger than the sum of the other two, your method should return false. For example, the call of dominant (4, 9, 2) would return true because 9 is larger than 4 + 2. The call of dominant (5, 3, 7) would return false because none of those three numbers is larger than the sum of the others. You may assume that none of the numbers is negative.
