Assume a strain gage is bonded to the cylinder wall surface in the direction of the hoop strain. the strain gage has nominal resistance r0 and a gage factor gf. it is connected in a wheatstone bridge configuration where all resistors have the same nominal resistance; the bridge has an input voltage, vin. (the strain gage is bonded and the wheatstone bridge balanced with the vessel already pressurized.)calculate the voltage change ∆v across the wheatstone bridge when the cylinder is pressurized to ∆p = 2.5 atm. assume the vessel is made of 3004 aluminum with height h = 21 cm, diameter d = 9 cm, and thickness t = 65 µm. the gage factor is gf = 2 and the wheatstone bridge has vin = 6 v. the strain gage has nominal resistance r0 = 120 ω.

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)?
