FirstHope Flow of fluids is the movement of a fluid (liquid or gas) from one location to another. It can be characterized based on various parameters such as velocity, pressure, and the type of fluid. Understanding fluid flow is essential in numerous engineering applications, including hydraulics, aerodynamics, and process engineering. Flow of fluids refers to the movement … Read more
Organization of Nervous System is divided into two main divisions: the Central Nervous System (CNS) and the Peripheral Nervous System (PNS). Each of these divisions has its own subdivisions and components, which work together to coordinate and control various functions in the body. 1. Central Nervous System (CNS): a. Brain: The brain is the control … Read more
Manometers are devices used to measure the pressure of fluids by balancing the fluid column against a known pressure. 1. Simple Manometers: Piezometer: Measures the pressure of a liquid column, usually open to the atmosphere. U-tube Manometer: Comprises a U-shaped tube filled with a liquid (often mercury or water) where one end is connected to … Read more
A neuron, or nerve cell, is the fundamental unit of the nervous system responsible for processing and transmitting information through electrical and chemical signals. Neurons are the building blocks of the brain, spinal cord, and nerves throughout the body. While there are various types of neurons with specialized functions, they all share a common structure: … Read more
Let’s Discuss Introduction of Nervous System in easy points: The nervous system is a complex network of neurons that transmit signals throughout the body, coordinating and controlling a wide range of functions, from voluntary movements to involuntary processes like homeostasis and internal organ regulation. Main Divisions: 1. Central Nervous System (CNS): Composed of the brain and … Read more
Equilibrium Moisture Content (EMC) is the moisture level where wood neither gains nor loses water, balancing with surrounding air humidity Measurements of Equilibrium Moisture Content 1) Hygroscopic Methods: Static Equilibrium Method: The material is placed in a controlled environment (constant temperature and relative humidity) until no further weight change occurs. Dynamic Method: The material is … Read more
Objectives of Drying Preservation: Removing moisture from materials to prevent spoilage and microbial growth. Weight Reduction: Reducing the weight for easier handling, storage, and transportation. Volume Reduction: Decreasing the volume for efficient storage and packaging. Consistency: Achieving a specific consistency or texture in products, particularly in food processing. Preparation for Further Processing: Preparing materials for additional processes … Read more
