Chapter 6, Problem 6.80P

Twenty m³/hr of air at 600 kPa, 330 K enters a well-insulated, horizontal pipe having a diameter of 1.2 cm and exits at 120 kPa. Assume steady state and use the ideal gas model for the air. Also assume constant specific heat, cp = 1.007 kJ/kg-K for air at 330 K. Determine the mass flow rate, in kg/s, and the exit velocity, in m/s. Step 1 Your Answer Determine the mass flow rate, in kg/s. mi = Step 2 Correct Answer (Used) 0.0352 * Your answer is incorrect. kg/s Determine the exit velocity, in m/s.

3. Air in a piston-cylinder assembly expands isentropically from state 1 where T1 = 40 °C to state 2, where the specific volume is twice that of state 1. Using the ideal gas model with k = 1.1, determine: a. T2 (°C) b. Work per unit mass (kJ/kg)

23 m³/hr of air at 600 kPa, 330 K enters a well-insulated, horizontal pipe having a diameter of 1.2 cm and exits at 120 kPa. Assume steady state and use the ideal gas model for the air. Also assume constant specific heat, c = 1.007 kJ/kg-K for air at 330K. Determine the mass flow rate, in kg/s, and the exit velocity, in m/s. Step 1 Determine the mass flow rate, in kg/s. m₁ = 0.04047 kg/s Step 2 Determine the exit velocity, in m/s. V₂ = 178.315 x m/s
