If d=0.25m and d=0.40m. assume headloss from the contraction to the end of the pipe can be found as hų = 0.9 (v is velocity in the pipe of diameter d). what height, h, will cause cavitation if atmospheric pressure is 100 kpa (abs)? what is the discharge when cavitation begins? water t-20°c

If a particle moves along a path such that r : (3 sin t) m and ? : 2t rad, where t is in seconds. what is the particle's acceleration in m/s in 4 seconds? a)- 16.43 b)- 16.29 c)- 15.21 d)- 13.79

Draw the engineering stress-strain curve for (a) bcc; (b) fcc metals and mark important points.

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)?
