CHAPTER 1: INTRODUCTION WATER;                Water is an inorganic, transparent, tasteless, odorless, and nearly colorless chemical substance, which is the main constituent of Earth's hydrosphere and the fluids of most living organisms. It is vital for all known forms of life, even though it provides no calories or organic nutrients. MECHANISM FOR PULLING WATER; 1.2 MACHINE DESIGN and Engineering Drawing It may also involve the application of other subjects, such as electrical theory, thermodynamics and hydraulics as in the design of electric motors and geaeotors, LC Engines and Steam engines and turbines, gas turbines, water pups, water (urbines and other hydraulic machines, ec, 1.1.1. SOME DESIGN DEFINITIONS I. Empirical Design: The design based on pust experience and existing practice is known as the ‘Empirical Design’. In this, various dimensions are set out as a proportion of certain main dimension, e.g, the various dimensions of a flange coupling are g

Forecasting conepts of PPC FORECASTONG A forecast is an estimate of the level demand to the expected for a production of several products for some period of time in the future. Forecast is made of sales ( in Rs.) or physical units under a proposed marketing or program & under an assumed set of economic & other force outside the unit system). Forecast should cover a time period at least as long as the period of time required to make the decision & to put that decision into effect. IMPORTANCE OF FORECASTING There are 3 major purposes. 1) To determine necessity for & the size of plant expansion ( Facility Forecast ) 2) To determine intermediate planning for existing products to be manufactured with existing facilities. 3) To determine Short-time scheduling of existing products to be manufactured on existing equipments ( Product Forecast ) Section 3 Section 4
