Fluid dynamics

control volume, operating at steady state. Pump: The liquid condensate leaving the condenser at the state 1 is pumped to the operating pressure of the boiler. The pump operation is considered isentropic. Boiler: The heat is supplied in the working fluid (feed water) in the boiler and thus vapour is generated. The vapour leaving the boiler is wther saturated at the state 3 or superheated at the state 311, depending upon the amount of heat supplied in the boiler. Steam power plant that operates…

Surface and center temperature of the mushroom, ambient humidity and temperature of vacuum chamber have been measured and recorded by the data logger inside the vacuum chamber (see Fig. 1). On the other hand, the control unit that records the pressure data is located outside the vacuum chamber (see Fig. 1). The measured data saved for each 10 seconds. Before starting the cooling, vacuum pump runs half an hour for stabilizing the system. Experiments carried out for three replicates and the…

Superfluid helium or He II is a macroscopic quantum fluid that exhibits extraordinary properties. %By applying the limit of low flow velocities, The behavior of the fluid can be understood using a Landau - Tisza model, where He II is considered to be a two-component fluid with independent velocity fields: the inviscid superfluid of density $\rho_s$, and the normal fluid of density $\rho_n$, where the total density $\rho$ = $\rho_s$ + $\rho_n$ \cite{Tisza,Landau}. The superfluid has neither…

Thermal properties of BHE The thermal properties of the ground are mainly determine by the minerals , water saturation and porosity. The thermal conductivity is depend upon porosity when the porosity increase thermal conductivity is gradually decrease due to that water and air are less conductive as compare to minerals, and on the other hand heat capacity increase with higher water content. During the installation of heat exchanger soil loss it structure due to drilling then the thermal…

Objective: In this laboratory experiment three objectives were sought after. These objectives were to first, create a separation scheme. Second, perform basic biochemical qualitative analytical tests. Lastly, identify the major components of milk. Introduction: The three goals in this experiment were desirable due to the fact that it gave knowledge on what is actually digested when milk is consumed. This is notably important to the children and adults that are lactose intolerant. 1 Many…

The viscoelastic behavior of bucky paper reinforced epoxy laminar composite materials for structural application has been evaluated through Dynamic Mechanical Analysis. The effects of heating rate, sinusoidal forces on glass transition temperature Tgwere studied. In DMA LVDT controlled sinusoidal force is applied and measures the response of the input as shown in the figure 3. It measures parameters which are the signature properties of the material under supervision like storage modulus, loss…

Differences in thermoregulation patterns observed in the Monarch Butterfly, Danaus plexippus Many Lepidoptera species thermo-regulate using several patterns, physical and behavioral. These patterns are usually observed as movements from the shade and cooler areas to a place exposed to the sun as well as utilizing mechanical flight to generate heat. However, some species have intermediate behavioral patterns, often a mixture of basking and heat production, also known as endothermy (Kingsolver…

The active region displayed in Figure 1 show a larger pore and several smaller pores in G-band. Bright points and several micropores are also visible. This active region was observed from 18:08 UT to 23:38 UT. However, there are three gapes from 18:42 to 19:08 20:21 to 20:47 and 21:59 to 22:26. Figure 1 shows the first image of the time series. Figure 2 illustrates the evolution of the fine structures at the inner part of the granules (i.e. towards umbra) at the pore boundary. Several dark…

The purpose of experiment six was to better understand how to measure and read volumetric flow rate of water through a pump, and to better understand how flow meters work. In this experiment, the relationship of the plot between the orifice and Venturi meter pressure differential showed many correlation with each other. The volumetric flow rate had a square root relationship with the previous stated pressure differentials. The error in this lab was also extremely low appearing at around…

relationship between flow and ∆P through a Venturi in a pipe at a various distances from the Venturi. THEORY: The Venturi flow meter is an equipment that uses the Bernoulli Effect and a manometer pressure gauge to measure the rate of flow of a liquid or fluid that is flowing through a pipe. There is also a part in the venture equipment that has a reduced cross-sectional area. When the liquid goes through this part, the speed (velocity) tend to…
