Formaldehyde (CH2O) is made by the catalytic oxidation of pure methanol vapor and air in a reactor. The product stream from this reactor contains: 63.70 moles N2, 13.40 moles O2, 5.30 moles H2O, 4.10 moles CH2O, 12.30 moles CH3OH and 1.20 moles HCOOH. The reaction is 2CH3OH + O2 A side reaction occurring is 2CH2O + O2 2CH2O + 2H2O 2HCOOH

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)?
