Prostate Inspection Model

Description

This model provides prostates with tumors in 4 different development periods. The 1st development: Beginning, a little big but the prostates still works well. The 2nd development: Some hard tubers can be served in the top right quadrant of prostate. It's the beginning of the tumors. The 3rd development: The tumor is proliferating, and the previous tubers become bumps. The 4th development: The prostates is all replaced by tumors, the surface become more rough and harder than before.

Thermal Conductivity Of Liquid

Thermal conductivity of is an important engineering property. The apparatus uses guarded hot plate method for determining thermal conductivity. It consists of hot plate i.e. an electrical heater sandwiched between two plates. The heat loss from hot plate is prevented by using two guard heaters and heat of removes heat from liquid by circulation of water. Input to heaters the temperatures.

Emissivity Measurement Apparatus

The apparatus consists of a test plate and a comparator. A black plate is used as a comparator for test plate. When all the physical, dimensions and the temperatures are equal, heat losses from both plates will also be the same, except radiation losses. Hence the input difference will be due to difference in emissive. Both the plates are kept in a panel enclose with perplex front and are given inputs through separate dimmerstats so that temperatures of both can be kept equal. Thus emissivity can determine over a wide range of temperatures.

SPECIFICATIONS:

1.Test plate and Black plates — 160mm. Dia. Aluminum plates, mounted in Panel with mica heater inside. 2.Instrumental panel consisting of- a)Voltmeter and ammeter for input measurement to both heaters through a selector switch. b)Separate dimmers for both the plates. c)Multichannel digital temperature indicator. A technical manual accompanies the unit.
