I. A well-insulated pipe of 2.54 cm inside diameter carries air at 2 bar pressure and 366.5°K. It is connected to a 0.0283 m³ insulated bulge, as shown. The air in the bulge is initially at 110 kPa pressure and 311°K. A and D are flow meters which accurately measure the air mass flow rate. Valves B and C control the air flow into and out of the bulge. Connected to the bulge is a 0.283 m³ rigid, adiabatic tank which is initially evacuated to a very low pressure. At the start of the operation, valve B is opened to allow 4.54 g/s of air flow into the bulge; simultaneously, valve C is operated to transfer exactly 4.54 g/s from the bulge into the tank. These flows are maintained constant as measured by the flow meters. Air may be assumed to be an ideal gas with a specific heat ratio y = Cp/C= 1.4, Cp=29.3 J/mol-K, and molecular weight = 29. Gas constant R = 8.314 m²³-Pa/mol. K. Air at 2 bar pressure A B 1) Determine the mass inside the bulge Bulge -10 dT 2) If the initial mass inside the bulge is 40 g, determine the initial dt Tank I.
