Procedure:-

1)How to enter the program

Esc->S->CR->CR->S.address (7000)->CR
Esc->S->CR->CR->Data (7500)->CR

2) How to execute the program

Esc->Go->CR->CR->S.address->CR

3)How to check the result

S->CR->CR->address (7450)->CR


Result:-

7450-58H

Estimation of total chlorophyll by Aron's method

-
Purpose:- Estimation of total chlorophyll by Arnon's method. Requirement:- Spectrophotometer Buchner's funnel, filter paper test tube, Fresh leaves. measuring cylinder pestle & mortar 80% Acetone  Formula:- 20.2 (A645) +802 A663) / 1000 x W Principle:- Chlorophyll is extracted in 80% acetone & the absorption at 660 nm& 645 nm are read in s spectrophotometer using the absorption co-efficient, the amount of chlorophyll is calculated Procedure:- 1) Weigh 1 gm of finely cut & well mixed representative sample of a leaf or fruit tissue into a clean mortar 2) Grind the tissue to a fine pulp with the addition of 20mil of 80% acetone   3) Centrifuge (5000 rpm for 5 min) & transfer the supernatant to a 100 ml volumetric flask  4) Repeat this procedure until the residue is colorless wash the mortar and pestle  thoroughly with 80% acetone and collect the clear washing in the volumetric flask 5) Make up the volume to 100 ml with 80% acetone  6) ...

Determination of Stefan's constant

Image
Aim:-  To determine the value of Stefan's constant. Apparatus:-  Black body radiation unit, Ammeter, Voltmeter, connecting wires, DC source. Theory:-  Stefan's constant: A physical constant denoted by  σ , is the constant of proportionality in the Stefan's-Boltzmann law- the total intensity radiated over all wavelength increases as the temperature increases Procedure:- 1) The electrical connections are made as shown in the circuit diagram. 2) Copper black body radiator is preheated to  30 0 C   by setting maximum voltage in the power supply 3)after the temperature indicator indicates a temperature of about    30 0 C , the voltage is reduced to some value  4) increase the voltage in steps of 0.2 V and note down the current, hence calculate power l. 5) Determine the value of Stefan's constan t. Observations:-  Room temperature t o =t+273=......of 2) surface area of the black body  A=4π r 2  = .........m square Calculati...

Pre-Emphasis & De-Emphasis Networks

-
Image
Aim:-  To draw the frequency response of Pre-emphasis & De-emphasis networks. Introduction:- Educational trainer a useful kit for the demonstration of Pre-emphasis & De-emphasis at different time constants & plot the graph of the frequency response of Pre-emphasis and De-emphasis networks. The kit consists of 200 Hz-20 kHz audio oscillator 70µ sec & 50µ sec De-emphasis networks.  Pre-Emphasis Circuit Diagram:- DE-Emphasis Circuit Diagram:- Theory:- Pre-emphasis refers to boosting the relative amplitudes of the modulating voltage for higher audio frequencies from 2 to approximately 15 kHz . De-emphasis means attenuating those frequencies by the amount by which they are boosted.  However, Pre-emphasis is done at the transmitter and De-emphasis is done in the receiver. The purpose is to improve the signal-to-noise ratio for FM reception. A time constant of 75µ sec is specified in the RC or L/Z network for Pre-emphasis and De-emphasis. Tabular colu...
