         Flow of fluids


★ May be definds as it is behaviour of fluids (liquid, gas). Which flow in open condition that do not permanently resist destortion.

Manometer-;

★ It is a device of instrument which is used to measure pressure difference.

Types of manometer- 
(1.) Simple manometer

(a.) U tube manometer

(b.) Piezometer

(c.) Single column manometer

•    Verticle single column manometer
•     Inclined single column manometer

(2.) Differential manometer

(a.) U tube differential manometer

(b.) Inverted U- tube differential manometer

Simple manometer-; Simple manometer are made up glass tubes . One end of those remain open to the atmosphere and the other hand are collected to the point were pressure to be measure.

Principle-;
★ It were one of the principle of hydrostatic equilibrium and is used for measuring pressure ( static pressure). 
★ Exceded by a stil liquid or gas , hydrostatic equilibrium state that the pressure at any point in a fluid at rest is equal end its value is just the weight of the over living fluids .
★ The manometer is the simplest instrument for gauge pressure low range pressure instrument alaning the pressure against the weight of a column in liquid.
★ The action of are manometer depend on effect of pressure exerted by a fluid at the depth.

Advantage-;
★ Simple and time proven.
★ High accuracy and sensitivity.
★ Fill fluids of varying specific gravity.
★ It have reasonable for.
★ Suitable for low pressure and low differential pressure application.

          //  Redox Titrations \\ • A Redox titration is a type of titration in which titrant and titrand react through and oxidation reduction reaction. • The end point of a Redox titration is detected by using indicators. Principles of Redox titration; Reduction—  • The subtances  can undergo reduction by followin. • The addition of hydrogen. •The removal of oxygen. • The acceptance of electrons. Example- fe³+→fe ²+  Oxidation— • Addition of oxygen. • Removal of hydrogen. • Loss/ donation of electrons. Example- fe²+ → fe³+ Oxidising agents;  •An oxidising agent is a chemical species that causes that other reactant in a redox reaction to be oxidized, and it is always reduced in the process. Example- Ag + , O², O³

Diabetes mellitus short notes -

               ;Diabetes mellitus; • Carbohydrate body turns it into a sugar called glucose and sends that to your bloodstream. • pancreas release insuline  Type 1 diabetes; • It's an autoimmune disease. • 10 % of people who have diabetes have type 1. • It was once better known as" Juvenile" diabetes • It is also called insulin dependent diabetes. Type 2 diabetes; • 95% of people have type 2 diabetes.   Symptoms of diabetes; • Increase thirst  • Weak, tired feeling. • Blurred vision . • Number or tingling in the hand or feet. • slow - healing sores or cuts. • unplanned weight loss. • Frequent urination. • Frequent unexplained infection. • Dry mouth  Treatment; • Diuretic • Drugs that ↑ insulin production. • Drugs that ↑ sugar absorption. • Nutritional & meal time. • Exercise, reduced stress. • Quit smoke& alcohol.
