Consider the liquid level system shown in Figure 1. At steady state, the inflow rate and outflow rate are both Ở and the flow rate between the tanks is zero. The heads at tank 1 and tank 2 are both H. At t = 0, the inflow rate is changed from 0 to + , where is the small change in the inflow rate. The resulting changes in the heads (h/ and h2) and flow rates are assumed to be...

Question 2 a) The following diagram show a liquid-level storage tank with q, and qi is the inlet and outlet volumetric flow rate of the tank. Ri is the resistance valve whereas Hi is the liquid level of the tank. Find the transfer function relating change in level, Qi', to the changes in flow rate into the tank, Q' (State your assumption) (10 marks) b) An electrically heated process is known to exhibit second order dynamics. The heater input change...

An important problem in chemical engineering separation equipment involves thin liquid films flowing down vertical walls due to gravity, as shown in this figure yV A. Assume that the wall is long and wide compared to the film thickness, with steady flow that is laminar and fully developed: u= v=0 and w w(x). Using a force balance on a rectangular differential element, derive an expression relating g, p, and τΧΖ . Use τΧΖ-n(-_ +--) for a Newtonian fluid to convert...

(40 pts) Shell-and-Tube Heat Exchanger to make Jell-O Cups A counter-current shell-and-tube heat exchanger is used to heat Jell-O solution (water + gelatin) using saturated steam on the shell side. Jell-O solution must be heated to at least 80 oC, poured into individual plastic cups, and then cooled to make the solid Jell-O cups. The Jell-O solution is heated with steam that enters the shell at 2.0 bar (Tsteam = 120oC) and exits as a saturated liquid. At this temperature...

Quantitative: In the 1950s liquid hydrogen was considered as a fuel for a new type of aircraft being developed, the SR-71 Blackbird (shown in Figure 1). Figure 1: The SR-71 Blackbird Early research on the project focused on which fuel to use for the Blackbird. Pratt & Whitney had a J-57 engine that was designed for kerosene and being considered for implementation on the Blackbird. The J-57 only took 5 months to convert to running on liquid hydrogen, however tests...
