In a shell-and-tube heat exchanger, under nominal condition a process stream (a liquid) is heated from 100oc to 200oc without any phase change using a heating medium in the tube side, temperature of which gets reduced from 300oc to 150oc. the process side has a bypass which remains closed under nominal condition. under nominal condition, there are equal resistances to heat transfer on shell and tube sides. it is desired that the process stream flowrate be increased by 30%, but it is desired that the process side pressure drop increases by only 44%. so the remaining portion of the inlet process stream for the desired scale up is bypassed and then mixed with the stream exiting the heat exchanger. what is the temperature of the process stream just at the outlet of the exchanger (i. e. before it mixes with the bypass) if the flowrate of the heating medium remains unchanged? considering turbulent flow condition, assume that the pressure drop in the process side is proportional to the square of its mass flowrate, i. e. 2

Aloaded platform of total mass 500 kg is supported by a dashpot and by a set of springs of effective stiffness 72 kn/m. it is observed that when the platform is depressed through a distance x = 12.5 cm below its equilibrium position and then released without any initial velocity; it reaches its equilibrium position in the shortest possible time without overshoot. find the position and velocity of the loaded platform 0.10 sec. after its release. if a further load of 400 kg is added to the platform, find, i) the frequency of damped vibrations, and i) the amplitude of vibration after 2 complete oscillations, given that the initial amplitude is 15 cm.

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.
