Question in image. i need help with q 2 BackgroundSiphoning, the process of using a tube to carry a liquidover a barrier and to a lower location, can be described wellbythe mechanical energy equation. In this assignment youwill analyse siphoning behaviour theoretically, and thenwill carry out an experiment using a plastic bottle andlength of tubing provided to you.The plastic bottle has a nominal volume of one litre.However, two marks have been placed on the side of thebottle such that the corresponding volume between the twoAZmarks is approximately AV = 650 cm3. The plastic tubinggiven to you has an inside diameter of D = 2 mm and alength of L = 100 cm. In the picture to the right, Az is thevariable distance between the liquid level in the bottle andthe tube outlet level.The diameter of the tube is small enough that the flow inside will be laminar, anorderly state of flow in which a = 2 in the mechanical energy equation. Furthermore,the friction (wterm canexpressed as wf = kFLuavgwhere k = 9.5s-1 is a friction constant for room-temperature laminar flow of water inthis particular tubing. L is end-to-end length of tube and yovg is the average velocity inthe tube. You may take the water density to be 999kg/m3.AnalysisForthis experiment the analysis will be performed first.1. Calculate the volumetric flow rate of the siphon (cm3/s), assuming that L=100cm,Az = 80 cm, and that there is no friction in the tube (w = 0). In order to get thevolumetric flow rate, you must first calculate ygvg:2. Predict the volumetric flow rate of the siphon (cm3/s), assuming that L = 100cm,Az = 80cm, and that there is friction in the tube (wi given by equation above).3. Repeat the flow rate calculation from number 2 with the following change: assume ahalf-length of tubing is used, with L = 50 cm and Az = 33 cm1

Steam generators are a type of heat exchanges that are used inpower plants to generate steam at desired pressure andtemperature (Fig. Q1.b). In a steam generator, saturated liquidwater at 30°C enters a 60-mm diameter tube at the volume flowrate of 12 L/s. After exchanging heat with hot gas, the waterchanges to steam and leaves the generator at a pressure of 9 MPaand a temperature of 400°C. During this process, the diameter ofthe water/steam tube does not change. Where necessary, assume air as an ideal gas and consider R = 287J/(kg.K), Cp = 1005 J/(kg.K), Cv = 718 J/(kg.K). (i) Calculate the steam mass flow rate and inlet velocity of the steam? (ii) What is the exit velocity of the steam? (iii) Calculate the rate of heat transfer (in MW) required tochange the phase of liquid water to steam.
