Ch.E. 421 Problem Set (Batch Drying) 4 Ch.E.a/b 13-15 November 2012 The solution of the problems are to be submitted as a team report at the end of the period. Please include honor code and the individual contribution of each team member. 1. A wet solid is dried from 36% to 8% moisture in 5 hours under constant drying conditions. The critical moisture is 14% and the equilibrium moisture is 4%. Calculate the time needed: a) To dry from 8 to 5.5% moisture b) To dry from 30% to 15% moisture c)

Mill‚ 670 North Commercial Street Suite 201 Manchester‚ New Hampshire 03101 ABSTRACT Sequencing batch reactors (SBR) are a flexible configuration of the activated sludge process‚ capable of providing low effluent nutrient levels. The SBR is fundamentally the same as any other variation of the activated sludge process‚ except that it operates in a batch draw and fill mode. The nuances of a batch operation must be understood and applied. This paper presents design considerations unique to the SBR

containers and beer cans fall into this category. In modern mass production plants‚ a high degree of automation and computerized information technology is used to reduce costs in order to remain competitive. Quality control utilizing statistical methods is very important since a lot of scrap can be generated in a hurry if production processes go out of whack. Batch production refers to a production control method whereby the range of products manufactured in a plant is made in batches. In the past

Little Field simulation. It was up to that team member to locate our weaknesses within the simulation and to bring it up to the entire group. Once the group was notified of a change that needed to be made‚ we would all decide together through a group text. After we all decided that the change was a good idea‚ we would let the team member who was in charge for the day know and he made the appropriate changes to the station. This proved to be our success in running the simulation; all team members

Managing Customer Responsiveness at Littlefield Labs Background Littlefield Laboratories (LL) has opened another lab. The new lab uses the same process as the lab in the assignment “Capacity Management at Littlefield Labs” — neither the process sequence nor the process time distributions at each machine have changed. On day 0‚ the lab began operations with three preparers‚ one tester‚ and one centrifuge‚ and an inventory of 160 test kits. This left the lab with $1‚000‚000 in reserves. Customer

Before the simulation started‚ our team created a trend forecast‚ using the first 50 days of data‚ showing us that the bottleneck station was at Station 1. On day 50 of the simulation‚ my team‚ 1teamsf‚ decided to buy a second machine to sustain our $1‚000 revenue per day and met our quoted lead time for producing and shipping receivers. On day 97‚ we changed Station 2’s scheduling rule to priority step 2. We noticed that the bottleneck was not just at station 1‚ but at all stations‚ and that buying

SIMULATION • WHAT is Simulation ? • WHY is Simulation required ? • HOW is Simulation applied ? • WHERE is Simulation used ? DEFINITION • Simulation is a representation of reality through the use of model or other device‚ which will react in the same manner as reality under a given set of conditions. • Simulation is the use of system model that has the designed characteristic of reality in order to produce the essence of actual operation. • According to Donald G. Malcolm‚ simulation

This simulation game was developed by Sisk (1976). Basically‚ there are ten imaginary countries (Shima‚ Myna‚ Ila‚ Usa‚ Pam‚ Bonay‚ Shivey‚ Lani‚ Ranu and Bili) and each of these countries has three key elements to be considered: defense‚ resources and demography. The main purpose of this game‚ understanding the importance of negotiation and interdependence between countries. I would like to make some changes in the game for my class. Every student or group will choose their imaginary country.
