wi, 1 h AP wi,2 R W AP h W w Mass flow rate h - Height A - Area R-Valve resistance p-Density P1 = 1, P2 = 1 A = 2, A2= 4 R = 3, R = 1 At nominal steady state: wi,1 = 20, wi2 = 30 Note: w is proportional to height (h) and inversely proportional to valve resistance (R) A. Find and enumerate (i.e. plug in numerical values) the following transfer functions (primes are neglected): H(s) W(s) W,1(S)' WL,2 (s) B. Assuming that w,1 and W,2 are manipulated variables, draw the fully-labelled open-loop diagram of the entire process and include the enumerated transfer functions (neglect the actuator and sensor) C. Assuming that wil is a manipulated variable and w,2 is a disturbance variable, draw the fully-labelled open- loop diagram of the entire process and include the enumerated transfer functions (neglect the actuator and sensor)
