Chapter 11, Problem 46P

Consider the feedback controlled blending system shown below, which is designed to keep theoutlet concentration constant despite potential variations in the stream 1 composition. The density of all streamsis 920 kg/m3. At the nominal steady state, the flow rates of streams 1 and 2 are 950 and 425 kg/min,respectively, the liquid level in the tank is 1.3 m, the incoming mass fractions are x1 = 0.27, x2 = 0.54. Noticethe overflow line, indicating that the liquid level remains constant (i.e. any change in total inlet flow ratetranslates immediately to the same change in the outlet flow rate). You may assume the stream 1 flowrate andthe stream 2 composition are both constant. Use minutes as the time unit throughout this problem.   Identify any controlled variable(s) (CVs), manipulated variable(s) (MVs),and disturbance variable(s) (DVs) in this problem. For each, explain how you know that’show it is classified.CVs: ___________, MVs: _____________, DVs: ______________ b)  Draw a block diagram…

A heat transfer experiment is conducted on two identical spheres which are initially at the same temperature. The spheres are cooled by placing them in a channel. The fluid velocity in the channel is non-uniform, having a profile as shown. Which sphere cools off more rapidly? Explain. V 1

The cardiovascular countercurrent heat exchnager mechanism is to warm venous blood from 28 degrees C to 35 degrees C at a mass flow rate of 2 g/s. The artery inflow temp is 37 degrees C at a mass flow rate of 5 g/s. The average diameter of the vein is 5 cm and the overall heat transfer coefficient is 125 W/m^2*K. Determine the overall blood vessel length needed too warm the venous blood to 35 degrees C if the specific heat of both arterial and venous blood is constant and equal to 3475 J/kg*K.
