In a continuous vertical cylindrical decanter, derive a formula to calculate the height, ZC, of the heavier liquid overflow leg. The pressure at the discharge point of the heavier liquid is given as 90% of the pressure on top of the fluid mixture. The heavier liquid's height is expressed as "ZB" and the lighter liquid's height as "ZA." The lighter liquid is denoted as "A," and the heavier liquid as "B." *Vapor pressure is not equal to atmospheric pressure.
A control valve is used to manipulate a liquid flowrate in the flowrate control loop. Figure 2 shows the flow characteristic of the control valve.Determine the following: i. Type of flow characteristic of the control valve.ii. Flowrate through the valve if the valve travel is 45%. Noted that the flowrate of the liquid is 70 000 lb/h when the valve is fully opened.iii. The maximum flow coefficient of the control valve, if the density of the liquid is half of the density of water and the pressure drop across the valve is 10 psi.

You are the mechanical engineer supervising the layout of a piping system. In a certain portion of the pipe, the specifications are as follows: length of pipe is 10m, inside diameter of 30cm, outside diameter of 30.5cm, maximum allowable speed of 15m/s and a coefficient of 0.003456. If the uncertainties are 0.02mm for length, 0.8mm for the diameters and 0.1mm/s for the velocity, what loss of head will be imminent in this pipe? With all the above uncertainties, what is the total uncertainty in the head loss?

Problem 12.4 solve the given problem: A 2-compartment vessel contains fluid in each section. For the first compartment, the fluid density is 1254 kg/m^3 and the second is 611.9kg/m^3. The partition is removed, allowing the liquids to mix. Determine the specific gravity of the mixture if the fluid masses are equal.
The pressure of a reactor vessel can be adjusted bychanging either the inlet or outlet gaseous flow rate. Theoutlet flow is kept fixed as long as the tank pressure remainsbetween 100 and 120 psi, and pressure changes are treatedby manipulating the inlet flow control valve. However, if thepressure goes higher than these limits, the exit gas flow isthen changed. Finally, if the pressure exceeds 200 psi, a ventvalve on the vessel is opened and transfers the gas to a storagevessel. Design a control scheme that meets the performanceobjectives.
