1-109E Consider a U-tube whose arms are open to the atmosphere. Now equal volumes of water and light oil (p 49.3 lbm/ft') are poured from different arms. A person blows from the oil side of the U-tube until the contact surface of the two fluids moves to the bottom of the U-tube, and thus the liquid levels in the two arms are the same. If the fluid height in each arm is 30 in, determine the gage pressure the person exerts on the oil by blowing. -Air Oil Water 30 in FIGURE P1-109E

A container holds 75.2 liters of Oxygen at 271.4K and a pressure of 3.87 atmospheres. How much heat is required to raise the temperature of this gas to 296.4K, holding the volume constant? Give your answer in kJ. Treat the gas as an ideal gas. Note: It is understood that your answer is in units of kilo-Joules, however do not explicitly include units in your answer. Enter only a number. If you do enter a unit ("kJ" in this case), you answer will be counted wrong.
