1. Briefly describe salt production from brine production to finished round cans. Salt is produce by drilling the surface for about 2‚400 feet below. Then‚ water is infused in this cave; thus‚ salt is dissolved with the water. The resulting brine is then pumped in the surface‚ boiled and when it evaporates‚ salt crystals will occur with some moisture but can be removed through the drying process. This happen continuously for about 6 weeks but there will come a point where output will reduce (normal

CH 3080 Process Equipment Design Problem set – IA 1. Crude oil‚ specific gravity of 0.887‚ flows through the piping shown in Figure. Pipe A is 50-mm Schedule 40‚ pipe B is 75 mm Schedule 40‚ and each of pipes C is 38-mm Schedule 40. An equal quantity of liquid flows through each of the pipes C. The flow through pipe A is 6.65 m3/h. Calculate (a) the mass flow rate in each pipe‚ (b) the average linear velocity in each pipe and (c) the mass velocity n each pipe. (d) What capacity and type of pump

many years and is widely used for waste stabilization‚ pollution control‚ improvement of manure quality and biogas production (Weiland‚ 2006). Biogas production from manure contributes to climate protection by reducing emissions of CO2 via substitution of fossil fuels and by reducing CH4 emissions from the manure during storage (Moller et al.‚ 2007). It is expected that biogas production will be instrumental in reaching European goals in the field of renewable energy. Due to the simultaneous advantages

Marybeth Brooks Physics Lab III Specific Heat Capacity Lab May 25‚ 2011 Abstract The specific heat capacity of various metals can be calculated and compared to accepted literature values. Dropping heated metal samples into a calorimeter filled with water and then measuring the change in the temperature of the system accomplished this. The metal samples were heated in a boiling water bath and were assumed to be at 100 C when they were removed. It was added to a calorimeter and stirrer

silicates ( Ca2SiO4); 51% tricalcium silicates (Ca3SiO5); and 11% tricalcium aluminate (Ca3Al2O6). When water is added‚ a number of complex hydration reactions take place. A typical idealized reaction can be represented as 2 Ca2SiO4(s) + 4 H2O(l) Ca3Si2O7. 3H2O(s) + Ca(OH)2(s). The hydrated silicate‚ called tobermorite gel‚ forms strong crystals that adhere by means of strong silicon-Oxygen bonds to the sand and aggregate (small rocks) that are mixed with the cement.

I. Introduction A buffer system is a mixture of a weak acid or a weak base and its salt (conjugate base or conjugate acid‚ respectively) that permits solutions to resist large changes in pH upon the addition of small amounts of hydrogen ions (H+) or hydroxide ions (OH-). If the same amount of the buffer is added‚ the pH may only change a fraction of a unit. Our blood is a good example of a buffered system. It is maintained under a pH of 7.4. Thus‚ buffers are important in many areas of chemistry

Social Carrying Capacity The use of parks and protected areas by visitors creates concern about appropriate levels of use because there are limits that define how much pressure from outside forces an ecosystem can endure before it experiences degradation‚ and there are thresholds that define visitor experiences. When researchers‚ park authorities‚ and policy makers are trying to determine appropriate usage levels of specific areas‚ they frequently rely on the rationale of carrying capacity‚ including

INTRODUCTION Production is a formal activity that adds value to goods and services‚ including creation‚ transport‚ and warehousing until used. Production is an organized process with specific goals. It implies the creation of a utility or services. Operation is that part of as organization‚ which is concerned with the transformation of a range of inputs into the required output (services) having the requisite quality level. Production function is ‘the part of an organisation‚ which is concerned
