1. Argon gas is compressed from 154 kPa and 25.6°C to a pressure of 702 kPa during an isentropic process. What is the final temperature (in °C) of argon? Assume constant specific heats. You need to look up properties and determine k for argon. Please pay attention: the numbers may change since they are randomized. Your answer must include 1 place after the decimal point 2. Helium gas expands in an adiabatic turbine steadily from 691°C and 907 kPa to 67 kPa at a rate of 0.14 kg/s. For an isentropic efficiency of 78%, determine the power (in kW) produced by the turbine. Please pay attention: the numbers may change since they are randomized. Your answer must include 1 place after the decimal point 3. Argon gas enters an adiabatic nozzle steadily at 814°C and 697 kPa with a low, negligible velocity, and exits at a pressure of 118 kPa. What is the highest possible velocity of helium gas at the nozzle exit? Assume constant specific heats. You need to look up properties and determine k for argon. Please pay attention: the numbers may change since they are randomized. Your answer must include 1 place after the decimal point 4. Air is compressed from 31.4°C and 3.9 L to a volume of 0.47 L in a reversible adiabatic manner. Determine the final temperature (in °C) of the air using the constant-specific-heats assumption. Assume k 1.4 for air. = 'n (_T) + FR (+5
