This paper is basically concerned with the computerization of the design activity of Condenser, vital equipment in Heat Exchanger Unit (HEU) of Ther- mal power plant required for condensing the steam and for further reclaimable purposes to achieve economy. This software will also provide facilities to maintain user profile and the respective work details. The study use a developed model which estimates software effort by studying and analyzing small and medium scale application software. Keywords: Condenser; Pressure Drop; Heat Load Parameter; COCOMO; Linear Regression Model 1. Introduction Design of power plant equipments, the sizing of equip- ments are reckoned for the economic and optimum de- sign. So, software has been developed to this effect. This paper will help in finalizing optimum equipments size for tendering and in turn winning orders by the company from the customers. It will provide facilities to maintain equipment profile including all the parameters and the work details required to compute “PRESSURE DROP” parameter for the power equipment like “CONDENSER”. A database is maintained with an aim to keep the records of all those employees who have attempted to access the software. For security purposes a password is also main- tained for the software [1]. 2. Types of Software The number of different types of software components for the development of life cycle and associate with the different means of verification and validation with them are mentioned bellow. There are two main different types are new and existing software. New software: all software written specifically for the application; Existing accessible software: typically soft- ware from a similar application that is to be reused and for which all the documentation is available; Existing proprietary software: typically a commercial product or software from another application that meets all or some of the current application requirements but for which little documentation is available; Configurable software: typically software that already exists but is configured for the specific application using data or an application specific input language. 2.1. Equipment Management The equipments related information, of different phases, would be stored in separate databases [2]. The usage of Notepad files has also been made to store the frequently accessible data. Design engineering or design authority organization, represented by power plant technical ser- vices or power plant design engineering. Responsible for:  Data collection, review, validation and input.  Component design basis verification.  Data entry organization.  Data update procedures.  Data update request.  Software Quality Assurance (SQA). Software Quality Assurance (SQA) also addresses soft- ware and hardware testing, and the concept of verifica- tion, validation and certification (V, V & C). Software testing and alignment with the appropriate software ver- sion and testing phase is tracked as well as interface rela- tionships. 2.2. Software Lifecycle The Software lifecycle is determined by a combination of technology lifespan and cost factors. Obsolescence for software occurs in different ways, and can be handled by upgrade (enhancement) or eventual replacement with more Copyright © 2012 SciRes. JSEA
