a mass flow rate of 20‚000 kg/h. It is to be cooled by water from a nearby river by circulating the water through the tubes within the condenser. To prevent thermal pollution‚ the river water is not allowed to experience a temperature rise above 10°C. If the steam is to leave the condenser as saturated liquid at 20 kPa‚ determine the mass flow rate of the cooling water required. Question 5: (20 points) Steam at 5 MPa and 600°C enters a two-stage 5MPa adiabatic turbine at a rate of 20 kg/s.

Brooke Strowd AP Biology Ms. Butler 28 January 2013 I. Title: Effect of a Catalyst on Reaction Rate II. Introduction: The basis of the experiment is the enzyme; an enzyme is a biological molecule that acts as a highly selective catalyst. By combining with a substrate‚ an enzyme is able to create a new product that helps the body function. (Ex. Lactose/Lactase) A substrate is a molecule an enzyme acts upon‚ the two combine at an area called an active site. This active site allows induced fit

are minimal changes and differences in the experiments. The sizes of the daphnia are also better to be kept around the same. Daphnia are really quick so picking something to measure in a two-hour interval made it easier to narrow it down to heart rate. Since we can control their space‚ meaning less area of movement we can see their heart better. This also meant it wouldn’t allow us to measure other things that require a larger area of movement which were the majority

different amount of sucrose concentrations. The higher molarity concentrations increased the movement of water to balance out the inside of the tube and the beaker. The greater amount of concentration gradient‚ in each tube‚ increased the rate of osmosis. This rate of osmosis is due to the net movement of water from an area of low concentration to an area of high concentration. Because the tubes had different concentrations‚ certain tubes gained more mass than others. Solution A had 0.6 molarity

divorce law have generally made it easier and cheaper to end marriages‚ but this is not necessarily the cause of the rising divorce rate. Legal changes reflect other changes in society‚ especially changes in attitudes. In particular‚ sociologists argue that social expectations about marriage have changed. Functionalist sociologists even argue that high divorce rates are evidence that marriage is increasing)‚ valued and that people are demanding higher standards from their partners. Couples are no

What is the rule of 72? Well… here’s the equation: Years to double = 72 / Interest rate DO NOT reread this equation. The rule of 72 is a hard rule to explain. I will do my best to try to explain it. The answer to ‘rule of 72’ gives us a number of years. This number of years tells us how long it takes to double our money. Let’s say you have 100 dollar. The ‘rule of 72’ helps us figure out how long it will take to have 200 dollars. Scenario 1: You have invested your 100 dollars in a 3%

The Causes of the Rising Divorce Rate There were once the moments that take their breath away‚ leaving their hearts pounding and throat thickening; there were once the ones whose name they secretly write down on their diaries and whose footsteps they can carefully distinguish from others’. They said that it was love and they got married. However‚ as time elapses‚ all the moments are turned into the agonized memory‚ sealed deep in their hearts‚ and covered with stain and dusk; all their beloved

1.1 Explain the sequence and rate of each aspect of development from birth to 19 years All infants‚ children and young people follow a basic pattern in development. The rate they develop will vary from child to child. This is because all children are individuals‚ however knowing what to expect and roughly what age to expect it (milestones) can help us recognize development issues (early recognition is essential). Development is broken down into five section although they are separate‚ they all interconnect
