Amass is connected by means of a spring to an elastic support. the static deflection due to the weirhs of this mass is so mm. the support is oscillated with simple hamonic motion at 2.0 hz and amplitude 10 ms. determine the amplitude of vibration of the mass if the damping is net nie. the mass is now damped in oil bath which cyerts a yesistance proportional to velocity, and the spring anchorage 13 oscillated as before. it is observed that the amplitude of vibration of the mass is now cne-fifth of its previous value. find the damping ratio, the phase angle and the relative amplitude between mass and support.

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.

Refrigerant 134a enters an insulated compressor operating at steady state as saturated vapor at -26°c with a volumetric flow rate of 0.18 m3/s. refrigerant exits at 9 bar, 70°c. changes in kinetic and potential energy from inlet to exit can be ignored. determine the volumetric flow rate at the exit, in m3/s, and the compressor power, in kw.
