TITLE Ohmic Heated Hydrodistillation of ‘Serai Wangi’. 1.0 INTRODUCTION 1.1 General Overview Hydrodistillation is a method to extract essential oil from various plant materials and was used to separate essential oil from Cymbopogon flexuosus (lemongrass). Mostly used by small scale producers of essential oils. In hydrodistillation the plant material is almost entirely covered with water as suspension in the still which is placed on a furnace. Water is made to boil and essential oil is carried

Q1 1.The environment organization: Complexity: simple Definition：a function of strength，number，and interconnectedness of the specific and general forces that an organization has to manage. The lose-knit culture reflects the agriculture origins of the company and its rural location as well as the nature of business‚ it will be safe to conclude that for the agriculture industry‚ the uncertainty of environment is low; the degree of complexity is simple. Dynamism: stable Definition：a

this lab is to determine the average convective heat transfer coefficient for forced convection of a fluid (air) past a copper tube‚ which is used as a heat transfer model. Introduction The general definition for convection may be summarized to this definition "energy transfer between the surface and fluid due to temperature difference" and this energy transfer by either forced (external‚ internal flow) or natural convection. Heat transfer by forced convection generally makes use of a fan‚ blower

Mr. Kenton should not accept the bid from West because it isn’t in the best interest of the company‚ but at the same time with the transfer policy that exists‚ it is really up to him what is in the best interests of his division. I believe he should accept the bid from Thompson because not only will it result in the lowest cost‚ but also it will encourage buying from within the company

described in this paper was to develop a simplified method of accurately estimating the impact of mixed convection on the cooling capacity of a ceiling radiant panel in mechanically ventilated spaces. The simplified correlation for mixed convection heat transfer was derived from established mixed and natural convection correlations. It was found that the total capacity of ceiling radiant cooling panels can be enhanced in mixed convection situations by 5% to 35% under normal operating temperatures. INTRODUCTION

Its starting point for getting the map‚ the first transfer function is second order but there is deviation in some points so we should improve the transfer function. 2 Hossein ShirGir‚ 146074 ‚ Dortmund ‚Germany FIG.1 G1 Comment: Transfer function is second order transfer function there is deviation should be improve

laboratory where the transfer of heat can be carefully monitored in a closed system. The measurement of heat transfer is called calorimetry. The device in which heat transfer is measured is called a calorimeter. A calorimeter can be a sophisticated device that isolates the reaction from its surroundings or it can be a simple device in which the reactants are in constant‚ close physical contact with the surroundings. In either case‚ it is important that temperature and heat transfer can be easily monitored
