Asection of pipe pertaining to a certain machine vibrates with large amplitude of compressor speed of 220 rp*. for arralyztng this system; spring mass system was suspended from the pipe to ict as an absoiber, a 1 kg absorber mass tuned to 220 cpm resulted in two resonant frequencies 188 and 258 cpm. what must be the mass and the spring stif& ress of the absorber if the resonant frequencies are to lie outside the range of 150 to 310 cpm?

Apump is used to circulate hot water in a home heating system. water enters the well-insulated pump operating at steady state at a rate of 0.42 gal/min. the inlet pressure and temperature are 14.7 lbf/in.2, and 180°f, respectively; at the exit the pressure is 60 lbf/in.2 the pump requires 1/15 hp of power input. water can be modeled as an incompressible substance with constant density of 60.58 lb/ft3 and constant specific heat of 1 btu/lb or. neglecting kinetic and potential energy effects, determine the temperature change, in °r, as the water flows through the pump.

The filament of an incandescent lamp has a temperature of 2000k. calculate the fraction of radiation emitted in the visible light band if the filament is approximated as blackbody

Assuming compressible flow of air and that the measurements are done at flagstaff a pitot static tube that gives the difference of total and static pressure measures 0.35 m of mercury. what is the velocity of air? assume the temperature to be 300k. (submit your excel or matlab calculation sheet)
