Given fixed displacement pump therefore flow rate Qp of pump is constant.Here pressure relief Valve sets the required pressure P1 by delivering Qcyl into cylinder and the remaining pressre will be delivered into tank by flow Qprv. Here Qp =Qcyl +Qprv
When the pump is switched on. The actual pump flow Qp is goes into cylinder
a)At this stage p1 will be 0 Mpag and starts to raise
b)At this stage Qcyl is 0.002 m3
when needle valve is closed
a)At this stage p1 is 7.5 Mpag which pressure is set in pressure relief valve
b)At this stage Qcyl is 0 m3 (as required pressure is attained and flow (Qp) from pump flows into Pressure Relief Valve as Qprv)

6. Consider the liquid-level system shown. Assume that the outflow rate Q(m/s) through the outflow valve is related to the head H by: Q=kVH = 0.01VH Also assume when the inflow rate Qi is 0.015m3/s the head is constant. At t=0 the inflow valve is closed, so there is no flow for t0. Find the time necessary to empty the tank to half the original head. The area of the tank is 2m2 TIL Capacitance c
Fluid Mechanics QUESTION 4 (a) What are the Energy Grade Line (EGL) and Hydraulic Grade Line (HGL) in a pipe system? (1 mark) A factory draws its water supply from a mountain lake located 75 m above the factory (a) without pump. The factory is at present been supplied via 300 m of 20 cm diameter cast iron pipe. For control purposes, there are five gate valves and one globe valve in the line, as well as three standard 90...
A pump transports water from Tank 1 to Tank 2 through a constant-diameter piping system as shown below (not to scale). The flow rate is controlled by two gate valves, the gate valve I controls the main pipeline, while the gate valve II controls the loop line from T-joint A to T-joint B. All pipes are galvanized steel pipe of diameter D = 4 in. It has a total length of Li2= 620 ft from tank 1 to tank 2....

Problem 4: Read Appendix 2 below (Sec. 1.4.1 of Kasap) and then solve. A metallic back contact is applied to the CdTe solar cell of Problem 1 using a set up similar to that described in Figure 1.74 (b) on the next page. To form the metallic back contact, two evaporation sources are used, Cu and Au. An initial 3 nm layer of Cu is deposited first and then 30 nm of Au is deposited. After these depositions, the sample...

10. Write a one-page summary of the attached paper? INTRODUCTION Many problems can develop in activated sludge operation that adversely affect effluent quality with origins in the engineering, hydraulic and microbiological components of the process. The real "heart" of the activated sludge system is the development and maintenance of a mixed microbial culture (activated sludge) that treats wastewater and which can be managed. One definition of a wastewater treatment plant operator is a "bug farmer", one who controls the aeration...
