    DROPWISE CONDENSATION APPARATUS

    Condensation is a phase change heat transfer process occurring in many industrial applications, such as in steam power plants, refrigeration plants etc. Thus this is one of the important heat transfer process present in mechanical and chemical engineering application. The condensation of Vapour on a surface is of two types: 1. Drop wise Condensation. 2. Film wise Condensation. This set up is designed for finding heat transfer co-efficient of two types of condensation and for visualization of these processes. It consists of a vertical frame. Condensation tubes are fitted inside compact glass cylinder. Steam generator is fitted at the backside of the cylinder. Steam comes directly from generator to cylinder. Two valves are fitted to control flow rate of water in individual tubes. Digital Temperature Indicator monitors temperatures. Pressure gauge and Rotameter can observe steam pressure and cold, water flow rates respectively. A Digital temperature Controller is provided for controlling the temperature of Steam. Water level indicator is provided to safeguard the heater. Condensate is measured by measuring cylinder.ExperimentsTo study the Film wise & Drop wise condensation of steam on a vertical surfaceVisualization of condensation process in drop wise as well as film wiseUtilities RequiredWater supply 5 lit/min (approx.)Electricity Supply: 1Phase. 220 V AC. 1.5 kWTable for set-up support

    EMISSIVITY MEASUREMENT APPARATUS

    The present Set-up is designed to measure the emissivity of test plate. The test plate comprises of a mica heater sandwiched between two circular plates. Black plate is identical with test plate, but its surface is blackened. As all the physical properties, dimension and temperature are equal; heat losses from both plates will be same except radiation loss. Hence the input difference will be due to difference in emissivity. Both plates are supported on individual brackets in a wooden enclosure with one side glass to ensure steady atmospheric conditions. Temperature Sensors are provided to measure the temperature of each plate and surrounding. Supply is given to heaters through separate variacs so that temperatures of both can be kept equal and is measured with Digital Voltmeter and Digital Ammeter.ExperimentsDetermining the Emissivity of a test plate.Study the variation of emissivity of test plate with respect to absolute temperature.Utilities RequiredElectricity Supply: 1Phase, 220 VAC, 4 Amp.
