The volume of your fuel oil at 100°C is 1000m3*1.065 = 1065 m3. The straight use of vegetable oils as fuel in diesel engines entails adjusting several physical properties such as density and viscosity. The straight use of vegetable oils as fuel in diesel engines entails adjusting several physical properties such as density and viscosity. You can target the Engineering ToolBox by using AdWords Managed Placements. Our academic experts are ready and waiting to assist with any writing project you may have. Properties, like temperature and pressure, influence the Kinematic viscosity. We've received widespread press coverage since 2003, Your UKEssays purchase is secure and we're rated 4.4/5 on reviews.co.uk. 1992. In this study the density and viscosity of several vegetable oils are studied within a wide variety of temperatures. The micro controller uses the count value of the timer to compute the viscosity of liquids. Some features of the site may not work correctly. = k (T- Tref) n ……………….. (2) Where k and n are constants. *You can also browse our support articles here >. The sigmoid function is implemented for both input and output to train the neural network. The range is from 0.91 to 0.93 g/cm3 between the temperatures of 15 °C and 25 °C. The block diagram of the microcontroller based viscosity measurement system is shown in Figure 1. The density of vegetable oil varies with each type and temperature. This instrument system permits to keep the temperature of the sample at any desired value and recording of time for the collection of 50 cc of sample to compute its viscosity and to send the data to personal computer to enable the computer processing of such data. Recalculation of density of oil for different temperature and pressure values. The neurons in the hidden and output layer have sigmoid functions . Comparing to water, whose density is 1.00 g/ml, cooking oil is less dense. Block I consists of keyboard and LCD display, which are interfaced with Port B and Port D of microcontroller. The analog temperature in the form of voltage is given to analog input of Port A and it is digitized by the microcontroller. The orifice is opened, the timer in the microcontroller is started, and the timer is stopped when the IR detector senses the level of sample. The cylinder is surrounded by a water bath, which can maintain temperature of the sample to be tested at required temperature by the solid-state relay and microcontroller. From the figures 2 and 3, it is observed that the measured kinematic viscosity of samples decrease with increase in temperature. The straight use of vegetable oils as fuel in diesel engines entails adjusting several physical properties such as density and viscosity. 24th May 2018 The error occurred in kinematic viscosity determination by the neural network concept is found to be less than 1%. Viscosity measurement and control has great importance in food industry and accurate knowledge of viscosity is necessary for various industrial processes . The system is highly reliable, ease of handling, less expensive and portable. An instrumentation amplifier kept in block E is designed to amplify (gain 250) the signal from the temperature sensor. The error can be minimized by increasing the number of training cycles and by changing the number of neurons in the hidden layer. Viscosity is a very important property of lubricating oil . Company Registration No: 4964706. Then, select a substance to calculate its weight based on specified volume and temperature. Kinematic viscosity is defined as the ratio of absolute viscosity to mass density and has the unit of m2/s. On repeated heating, the composition of oil saturates leads to increase the level of LDL cholesterol, affects digestion capability, increases blood pressure and spoils function of human heart.

In the training pattern the input vectors is temperature of the sample and the output vector is kinematic viscosity. ( 2) for each oil and temperature are also shown. The input and output vectors which are obtained from the experiments is used for learning. In this process, the weights are modified and the system is trained so as to get the desired output for a given input. Calculate how much of this gravel is required to attain a specific depth in a cylindrical, quarter cylindrical or in a rectangular shaped aquarium or pond [ weight to volume | volume to weight | price ], Potassium tetrahydroborate [BH4K or KBH4] weighs 1 110 kg/m³ (69.29504 lb/ft³) [ weight to volume | volume to weight | price | mole to volume and weight | mass and molar concentration | density ], Volume to weight, weight to volume and cost conversions for Refrigerant R-22, liquid (R22) with temperature in the range of -51.12°C (-60.016°F) to 71.12°C (160.016°F), A picometer per second squared (pm/s²) is a derived metric SI (System International) measurement unit of acceleration. Stimuli are transmitted from one processing element to another via synapses or interconnections, which can be excitatory or inhibitory.
