A gas stream consisting of 15 mol % SO2, 20 mol% O2, and 65 mol% Nz is fed to a reactor at 250 °C and atmospheric pressure. 86% of the SO2 entering the reactor is oxidized to SO3. The effluent from the reactor leaves at 400 °C. Based on this, answer the following two questions: 1. Using a basis of 100 mol/hr of gas mixture fed, determine the molar flow rate of products in the effluent stream. 2. Calculate the heat required for this process. As part of this, set up (construct or draw out) the process path that you use to calculate the heat required. Label it carefully so we can understand your calculations and solution strategy.

Ahouse has the following electrical appliance usage (1) single 40w lamp used for 4 hours per day (2) single 60w fan used for 12 hours per day (3) single 200w refrigerator that runs 24 hours per day with compressor run 12 hours and off 12 hours find the solar power inverter size in watt with correction factor of 1.25.

Asteel wire of 2 mm diameter is fixed between two points located 2 m apart. the tensile force in the wire is 250n, if its density of steel is given by 7830 kg/m3 the fundamental frequency of vibration hz? ?

An external consultant recommends that a plant installs a bank of capacitors for power factor correction. this will reduce the peak electrical demand charges by an average of 93 kw every month. the plant current pays $13 per kw in peak demand charges. the capacitor bank will include 223 kw of fixed capacitors, and 183 of variable capacitors. the fixed capacitors cost $59 per kw, and the variable capacitors will cost $65 per kw. the consultant charges 21% of the equipment costs to install the capacitors. because this project will reduce the demand for the electric utility, they are prepared to provide a one-time rebate of $42 per kw of reduced demand. what is the simple payback period for this project (in years)?
