HEAT TRANSFER IN AGITATED VESSEL MAKE: CREATIVE LAB MODEL NO:-CLHT-05

DESCRIPTION:

In most industrial processes including reactors, heat is to be added or extracted to control the process. The addition and removal of heat is done by passing steam or water in a jacket fitted to the outside of the vessel or passing steam or cold water in helical coil inside the vessel. For effective heat transfer and even distribution of heat, the liquid inside is continuously agitated. The present set-up offers us a comparative study of Jacket & Helical coil, which can be operated simultaneously. It is a stainless steel jacketed vessel with helical coil of copper is fitted inside. A variable speed stirrer is fitted in the vessel. Variation in temperature of inside water is measured and is noted. Set-up is fitted with steam traps for condensate collection. Flow rate of water can be controlled and measured using valve and Rotameter. Temperature of inlet and outlet of both hot & cold fluids are measured by temperature sensors.

EXPERIMENTATION:

To determine the overall heat transfer co-efficient for various degree of agitation.

To make a comparative study of Heat Transfer through Jacket & Coil in an agitated vessel.

UNSTEADY STATE HEAT TRANSFER UNIT MAKE: CREATIVE LAB MODEL NO:-CLHT-06

DESCRIPTION:

The apparatus consists of a small test cylinder. The cylinder is Heated by a constant temperature water bath, till steady state is reached. During heating, temperature of the cylinder is function of time and hence, heating of cylinder is under unsteady state Heat transfer. The temperature of cylinder is measured with the help of temperature sensor inserted in the centre. The hot water bath is provided with a heater and is controlled by digital temperature controller. An agitator is also provided to maintain the constant bath temperature.

EXPERIMENTATION

To calculate the Biot number, Fourier number and hence the heat transfer coefficient.

To plot Heisler Chart for the given sample of cylindrical solid.

UTILITIES REQUIRED

Electricity Supply: 1 Phase, 220 V AC, 1 kW.

Bench area of 1.5 m x 1.5 m.

TECHNICAL DETAILS

Water Bath: Material - stainless steel Capacity-8 lit. (Approx.)

Stirrer for Bath: Stainless Steel Impeller with shaft coupled to a FHP motor.
