2: Air Pressure and Atmospheric Circulation

Air Pressure

• Force exerted by the weight of air on Earth's surface.
• Measured by barometer.
• Standard sea-level pressure = 1013.25 mb (hPa).

Factors Affecting Air Pressure

1. Temperature
2. Altitude
3. Water vapour
4. Earth's rotation

Explain Breaking Loop Method for Minimum Number of Heat Exchangers

1. Breaking loop method is used in Heat Exchanger Network (HEN) design to reduce the number of heat exchangers. 2. In a Heat Exchanger Network, loops are formed when streams are connected in a closed path. 3. Presence of loops increases the number of exchangers and overall installation cost. 4. The main objective of breaking loop method is to achieve minimum number of heat exchangers.  5. In this method, one heat exchanger from

Heat exchange and networking 1. Heat exchanger is a device used to transfer heat from one fluid to another without direct mixing of fluids. 2. In a heat exchanger, hot fluid loses heat while cold fluid gains heat. 3. Heat exchangers are widely used in chemical, petroleum, food and power industries. 4. Common types of heat exchangers are shell and tube, double pipe and plate heat exchangers. 5. Heat exchangers help in heating, cooling, condensation and evaporation processes. 6. Heat exchangers improve

UNIT 1. Q1. What do you mean by Tax Management? Explain its features and scope. Also differentiate between tax planning, tax avoidance and tax evasion.

1. Introduction

Tax is a compulsory financial obligation imposed by the government on individuals and organizations to finance public expenditure. In this context, tax management plays a significant role in ensuring that taxpayers fulfill their legal responsibilities while minimizing their tax liability. It helps in maintaining financial discipline,

Q.1&2. Brief about the physical deterioration of concrete. Ans:- 1)Physical deterioration of concrete refers to the damage or reduction in strength of concrete due to physical actions such as temperature changes, abrasion, erosion, and moisture variation. It affects the durability and service life of structures.2)Freeze-thaw action is one of the major causes of deterioration in cold regions. Water inside concrete pores freezes and expands, causing cracks and surface scaling.3)Abrasion

Q)Explain XML parser and its type.

An XML parser is software/library used to read and process XML documents.It checks XML syntax and converts XML data into usable form.

Types of XML Parsers

1) DOM Parser (Document Object Model)

Loads complete XML document into memory.

Represents XML as tree structure.

Allows reading and modifying XML.

Features - Easy navigation

Supports editing

Memory consuming

2)SAX Parser (Simple API for XML)

Reads XML line by line.

Event-driven parser.

Faster and memory efficient.

Return -1 if the weight is less than 0 or greater than 100. • Return 10.00 if the weight is between 0 and 10 kg. • Return 20.00 if the weight is between 10.01 and 20 kg. • Return 50.00 if the weight is between 20.01 and 50 kg. • Return 100.00 if the weight is between 50.01 and 100 kg.

Java Method

public static double calculateShippingCost(double weight) {
    if (weight < 0 || weight > 100) return -1;
    if (weight <= 10) return 10.00;
    if (weight <= 20) return 20.00;

6. Explain the concept of Weighted Average Cost of Capital with suitable examples.

Meaning

Weighted Average Cost of Capital (WACC) is the average cost of all sources of finance weighted according to their proportion in the capital structure.

Importance

Used as discount rate in capital budgeting

Measures overall cost of finance

Helps in capital structure decisions

WACC represents the minimum required return expected by investors and creditors.

7. Describe Modigliani–Miller (MM) approach
