• After a few weeks, the tissue samples will have grown into...read more

Primary hardening is the initial hardening of a material, while secondary hardening is a delayed hardening process.

• Primary hardening occurs during rapid cooling from high temperatures, while secondary hardening occurs at lower temperatures over a longer period of time.

• Primary hardening is due to the formation of martensite, while secondary hardening is due to the precipitation of fine carbides.

• Secondary hardening can result in an increase in strength and toughness of the mate...read more

Plant tissue culture is the process of growing and maintaining plant cells, tissues, or organs in a sterile and controlled environment.

• It involves the use of aseptic techniques to prevent contamination

• Plant tissue culture can be used for micropropagation, genetic modification, and conservation of rare or endangered plant species

• Commonly used techniques include callus culture, organogenesis, and somatic embryogenesis

• Applications of plant tissue culture include production of di...read more

Interstate sales are between two different states while intrastate sales are within the same state.

• Interstate sales involve movement of goods across state borders while intrastate sales do not.

• Interstate sales are subject to Central Sales Tax (CST) while intrastate sales are subject to State VAT.

• Interstate sales require additional documentation such as Form C while intrastate sales do not.

• Example of interstate sale: A company in Delhi selling goods to a customer in Mumbai. Ex...read more

There are four types of irrigation: surface, sprinkler, drip, and subsurface.

• Surface irrigation involves flooding or furrowing the land.

• Sprinkler irrigation uses overhead sprinklers to distribute water.

• Drip irrigation delivers water directly to the roots of plants.

• Subsurface irrigation involves placing water below the soil surface.

Filtration systems can be categorized into mechanical, biological, and chemical types.

• Mechanical filtration involves physically removing particles from a fluid, such as using a mesh screen or filter paper.

• Biological filtration uses living organisms to break down and remove contaminants, such as in a wastewater treatment plant.

• Chemical filtration involves using chemicals to remove impurities, such as activated carbon filters in water treatment.

• Other types of filtration systems...read more

I believe the farm bills have both positive and negative aspects.

• The bills aim to liberalize the agricultural sector and provide farmers with more options to sell their produce.

• However, there are concerns about the impact on small farmers and the potential for exploitation by large corporations.

• The bills have also faced opposition from farmers and political parties.

• Overall, a balanced approach is needed to ensure the welfare of farmers and the growth of the agricultural secto...read more

Irrigation systems are essential for providing water to crops efficiently. Types include drip, sprinkler, pivot, and flood irrigation.

• Irrigation systems help ensure crops receive adequate water for growth and production

• Types of irrigation systems include drip irrigation, sprinkler irrigation, pivot irrigation, and flood irrigation

• Drip irrigation delivers water directly to the roots of plants, minimizing water waste

• Sprinkler irrigation mimics rainfall by spraying water over cr...read more

Embedded automation is used for specific tasks while PLC automation is used for controlling entire systems.

• Embedded automation is used for a single task or function, such as controlling a motor or sensor.

• PLC automation is used for controlling entire systems, such as a manufacturing plant or assembly line.

• Embedded automation is typically programmed in low-level languages such as C or assembly, while PLC automation is programmed using ladder logic or other high-level languages....read more

A transformer is an electrical device that transfers electrical energy from one circuit to another through electromagnetic induction.

• Transformers are used to increase or decrease the voltage of an alternating current (AC) power supply.

• They consist of two coils of wire, known as the primary and secondary coils, which are wrapped around a magnetic core.

• When an AC voltage is applied to the primary coil, it creates a magnetic field that induces a voltage in the secondary coil.

• Tra...read more

Micro irrigation design parameters are the factors that affect the design of a micro irrigation system.

• Water source and quality

• Crop type and spacing

• Soil type and texture

• Topography and slope

• Climate and weather patterns

• System layout and components

Creating a work plan for fitting connection involves assessing site conditions, selecting appropriate materials, measuring and cutting pipes, assembling components, and testing for leaks.

• Assess site conditions to determine the best location for the connection

• Select appropriate materials such as pipes, fittings, and connectors

• Measure and cut pipes to the required length

• Assemble components in the correct order following manufacturer guidelines

• Test the connection for leaks befor...read more

CT stands for Current Transformer and PT stands for Potential Transformer.

• CT is used to measure high current levels by stepping down the current to a lower level.

• PT is used to measure high voltage levels by stepping down the voltage to a lower level.

• Both CT and PT are used in power systems for protection and metering purposes.

• CT and PT are also used in testing and commissioning of power systems.

• Examples of CT and PT include Wound Primary CT, Bar Primary CT, Capacitor Voltage ...read more

Instruments used to calculate flow rate.

• Flow meters

• Pitot tubes

• Rotameters

• Turbine flow meters

• Ultrasonic flow meters

Pressure is defined as force per unit area.

• Pressure = Force / Area

• The SI unit of pressure is Pascal (Pa)

• Other units of pressure include bar, psi, atm, mmHg

• Pressure can be measured using instruments such as manometers and pressure gauges

Duty in irrigation refers to the amount of water that needs to be applied to a specific area of land to meet the water requirements of the crops being grown.

• Duty is calculated based on factors such as crop type, soil type, climate, and evapotranspiration rate.

• It is usually measured in terms of depth of water (in inches or millimeters) that needs to be applied to the land over a specific period of time.

• Proper calculation of duty ensures that crops receive the right amount of w...read more
