The flow rate through hose and nozzle is 0.500 L/s. Calculate the speed of the water (a) in the hose and (b) in the nozzle. 7 Page 1 4. A container filled with water and there are two holes, as shown in the figure below. What is the ratio of x to x? 20 cm 100 cm 50 cm; X X2 5. You do 25 kJ of work on a system consisting of 3.0 kg of water by stirring it with a paddle wheel. During this time, 15 kcal of heat is released by the system due to poor thermal insulation. What is the change in the internal energy of the system? 6. During a thermodynamic process, a system moves from state A to state B, it is supplied with 400 J of heat and does 100 J of work. (a) For this transition, what is the system's change in internal energy? (b) If the system then moves from state B back to state A, what is its change in internal energy? (c) If in moving from A to B along a different path, W'AB = 400J of work is done on the system, how much heat does it absorb? 2 of 2 ||
