conducted was to analyse the work of a heat exchanger‚ by studying the effects of heat transfer from a hot stream and a cold stream in the heat exchanger. In the experiment we were introduced to the shell and tube heat exchanger and were told of all its parts and how to use them. The experiment started by evaluating what the heat transfer rate for a hot stream and a cold stream was within the heat exchanger. Using this information the experiment went on to analyse the heat exchanger in more detail. The log

chapter 6: Planning capacity Capacity the maximum rate of output of a process or a system. Acquisition of new capacity requires extensive planning‚ and often involves significant expenditure of resources and time. Capacity decisions must be made in light of several long-term issues such as the firm’s economies and diseconomies of scale‚ capacity cushions‚ timing and sizing strategies‚ and trade-offs between customer service and capacity utilization. Planning capacity across the organization

can be used most successfully. Fish for stewing include fresh water and ocean fish and shellfish. When stewing fish‚ gentleness is a must. If fish is cooked too vigorously‚ the flesh will break up and the fish protein toughens. Root vegetables‚ potatoes and fruit are suitable for stewing. Ratatouille is a vegetable stew‚ which includes onions‚ garlic‚ eggplant‚ zucchinis‚ tomatoes and capsicums. Fruits are usually stewed in syrup. Apples‚ rhubarb‚ figs‚ peaches and pineapples can be used. The stewed

Cross Flow Heat Exchanger Experiment By Andres Rodriguez Abstract The design project of the group was to create an experiment for Thermo/Fluids Laboratory. The experiment will help aide the students in relating pressure drop and heat transfer in a cross flow heat exchanger. The experiment consists of three cross flow heat exchangers (bare inline‚ bare staggered‚ and finned staggered) that will cool hot water with current fan in the Laboratory. Optimal flow rates‚ pressure and temperature

Title: Heat Treatment of Ferrous Objective: To determine the effect of heat treatment on mechanical properties of 1050 Steel. To reveal the microstructures of 1050 steel during heat treatments. Abstract In this experiment‚ we observed how the properties of plain carbon steel vary with the heat treatment condition. We prepared six different samples in three different heat treatment configurations and performed hardness tests on them by using the Rockwell tester and observed the microscopic

here to present to you about my specific fear. Fear‚ the mere sight of the word makes us cringe. It is a feeling we have all dealt with at one time or another. It is a feeling that we first experience when we are small‚ and are conditioned to respond to in many different ways. Some of us live in constant fear; of accidents‚ of bad people doing us harm‚ or of physical ailments. Everybody in the world which we reside has a fear of something‚ including me. The specific fear of mine is the moment when

AND BUFFER CAPACITY INTRODUCTION A buffer solution is one in which the pH of the solution is "resistant" to small additions of either a strong acid or strong base. Buffers usually consist of a weak acid and its conjugate base‚ in relatively equal and "large" quantities. A buffer system can be made by mixing a soluble compound that contains the conjugate base with a solution of the acid such as sodium acetate with acetic acid or ammonia with ammonium chloride. The buffer capacity refers to
