EFFECT OF Al2O3 NANO PARTICLE ADDITION ON TEMPERATURE AND TIME REQUIRED FOR COOLING

Set up: Fig: Set up Layout
Setup Description
1. The test rig shown in fig has been used to measure heat transfer coefficient and friction factor in the automotive engine radiator. This experimental setup includes a reservoir steel tank, electrical heater, a pump, a rotameter, hose pipes, flow control valves, a fan, Power supply, K type thermocouples for temperature measurement, and automobile radiator (heat exchanger).

2. An electrical heater (1000W) inside a steel storage tank of 12 ltr capacity (45cm height and 30 cm diameter) put to represent the engine and to heat the fluid. AC mains power supply provide the power to keep the inlet temperature to the radiator from 80 to 100ₒC. A rotameter (500–2500 LPM) and two flow control valves used to measure and control the flow rate. The fluid flows through hose pipes (0.5in.) by a pump (0.5 hp and 30-40 m head) from the tank to the radiator at the flow rate range 500-550 LPM. The total volume of the circulating fluid is 3lts and constant in all the experimental steps.

Thermocouples of type K, one has been fixed on the heater (T1). Then next two thermocouples are kept in the radiator inlet and outlet tank for recording the inlet (T2) and outlet (T3) fluid temperatures.

4. For the air, a fan (1500-2000 rpm) is installed close on axis line of the radiator. The AC power supply is used to run the fan.

5. Testing is done at constant conditions as when temperature of heater temperature reaches 80oC then pump gets started and fluid will remain in circulation till T1 reaches 500C, and time is noted for this

The pitch is angled triangular, as this is a preferred method Sinnott (2005). (Eq. 3.4 6) is used to calculate the number of holes per tray: The number of holes per tray above feed stage is 25912, while below feed stage the number of holes is 24793. The choice of hole diameter is usually about 5mm, but an increase in the size of the hole can be considered when fouling causes concern (Sinnott, 2005). The minimum hole size is about twice the size of plate thickness for stainless steel, in this case…

Chapter Three Design Principles and Implementation 3.1 Overview This chapter deals with the use of the MATLAB software to design the digital-mixer. At first the idea of using the Graphical User Interface for MATLAB was looking promising as it provides a more classic and neat look compare Simulink model. But using the GUI in MATLAB was a very tedious task with all the coding and errors that arose. Therefore, Simulink was chosen as it provides a more direct approach to design the digital mixer…

of 18 test tubes, placing 3 test tubes in each of the 6 test tube racks; one test tube rack for each variable. This includes 3 test tubes for each variable to find an average and reduce the effect of anomalies making the results more reliable. 2. Then using a pipette extract 4ml of algal solution (Tolypothrix) from the beaker and place in a test tube. Repeat this for all 18 test tubes making sure that the measurement is read from the meniscus to ensure reliability. 3. After this, using a new pipette…

Post Lab Questions 1. Based on the amount of yolk, describe the egg type and cleavage pattern of a starfish. Isolecithal, they allow for complete cleavage through the entire egg. They have very little amount of yolk and are uniformly distributed. 2. What is the difference between a'smart' and a'smart'? Is the entire zygote of a starfish involved in early cleavage? Explain the adage of the adage. ? no it is holoblastic (the division of the entire egg into blastomeres). This allows for complete cleavage…

Basics of a-Si:H/uc-Si:H tandem solar cells Figure 1.2 shows the scheme of the one of the possible configuration for the thin-film tandem solar cell, which consists out of three blocks: the upper thin-film part, the thick layer of Silicon wafer and the bottom thin-film part, which are built in stack. Figure 1.2. The schematic view of the HIT solar cell According to Schockley the energy of photons, which exceeds the band gap is lost due to the thermalization of the charge carriers to the band edges…

This manuscript developed a HIF-1α stabilizing wound dressings by incorporating dimethyloxalylglycine (DMOG) in electrospun core-shell nanofibers. The authors showed the advantages of the material fabricated by the characterization, the release test, cell culture experiment and animal experiments. However, the reviewer thought that the detailed description of electrospinning process is incomplete. Following the precise analysis of the structure and the amounts of drug incorporated in fibers, the…

3.1.5.3. Coverslip culture technique Coverslip culture technique was used for reviewing the morphological characteristics of the marine actinomycetes isolates (Pridham et al., 1958). Sterile glass cover slips were inserted at an angle of 450 into solidified SCA medium in petri plate. A loopful of inoculum of each isolate was streaked laterally to the line where the coverslip come across the agar and then the plates were inoculated at room temperature (28±200C) for 7 days. After the development of…
