A binary system of species 1 and 2 consists of vapor and liquid phases in equilibriumat temperature T. The overall mole fraction of species 1 in the system is z1 = 0.65. Attemperature T, ln1 = 0.67 x22; ln2 = 0.67 x12; P1sat = 32.27 kPa; and P2sat = 73.14 kPa.Assuming the validity of Eq. (13.19),Final PDF to printer13.10.

You have been assigned the task of reviewing the relief scenarios for a specific chemical reactor in your plant. You are currently reviewing the scenario involving the failure of a nitrogen regulator that provides inert padding to the vapor space of the reactor. Your calculations show that the maximum discharge rate of nitrogen through the existing relief system of the vessel is 0.5 kgls, However, your calculations also show that the flow of nitrogen through the l-in supply pipe will be much greater than this. Thus under the current configuration a failure of the nitrogen regulator will result in an over pressuring of the reactor. One way to solve the problem is to install an orifice plate in the nitrogen line, thus limiting the flow to the maximum of 0.5 kg/s. Determine the orifice diameter (in cm) required to achieve this flow. Assume a nitrogen source supply pressure of 15 bar absolute. The ambient temperature is 25C and the ambient pressure is 1 atm. 3.

A power cycle receives QH by heat transfer from a hot reservoir at TH = 1200 K and rejects energy QC by heat transfer to a cold reservoir at TC = 400 K. For each of the following cases, determine whether the cycle operates reversibly, operates irreversibly, or is impossible.a.QH = 900 kJ, Wcycle= 450 kJ b. QH = 900 kJ, Qc = 300 kJ c. Weycle = 600 kJ, Qc= 400 kJ d. = 75%
