Absolute entropy is entropy calculated relative to the absolute reference point determined by the third law of thermodynamics. Absolute humidity (specific humidity or humidity ratio) is the mass of water vapor present in a unit mass of dry air; that is‚ it is the ratio of the mass of water vapor to the mass of dry air in atmospheric air. Absolute pressure is the actual pressure at a given position and it is measured relative to absolute vacuum (i.e.‚ absolute zero pressure). Throughout this

EXERCISE 9 - Mechanical properties of solid and fluid mechanics 1. A stainless-steel wire of length 3.1 cm and a diameter of 0.22 mm. If it is stretched by 0.10 mm‚ find the tension of the wire. The Young’s modulus for stainless steel is 18 × 1010 Pa. 22 N 2. Determine the elongation of the rod i Figure 1 if it is under a tension of 5.8 × 103 N. Young’s Modulus: Copper‚ 11.0 x 1010 Nm-2‚ Aluminium 7.0 x 1010 Nm-2 1.9 cm 3. Air is trapped above liquid ethyl alcohol in

transmission fluid‚ you need to act quickly in order to prevent your transmission from becoming damaged. If you have noticed transparent red or pinkish fluid under your vehicle‚ that is a very clear sign that your vehicle is leaking transmission fluid. Luckily‚ you can easily stop your vehicle from leaking transmission fluid‚ at least for a while‚ with this quick and easy fix. Locating Your Transmission Fluid Fill On the majority of automatic transmission vehicles‚ the transmission fluid tube is located

ABOUT ORAL FLUID DRUG TESTING N3 Fact #1 – The use of oral fluid testing is growing each year.1 Oral fluid drug testing in the workplace is relatively new compared to laboratory-based urine testing. But in a fairly short period of time it has become the testing method of choice for many companies. While it will not meet the needs of every employer‚ because of its unique advantages it will appeal to many

between the optimum pH and the pH used in the experiment‚ hence the enzyme structure is not affected by the pH and is most active. However the graph inadequately supports the second part of the prediction‚ that the rate will be lowest‚ the more acidic or alkaline the pH level is. For instance when the rate starts of low on pH 4 (0.2) and starts to gradually increase. However it only increases until pH 5 (0.29)‚ from that point‚ the rate decreases at pH 6 (0.116). Therefore the rate for pH 6 is

Basic equations of fluid statics | | | | | | | | | | | | | | | | An equation representing pressure field P = P (x‚ y‚ z) within fluid at rest is derived in this section. Since the fluid is at rest‚ we can define the pressure field in terms of space dimensions (x‚ y and z) only. Consider a fluid element of rectangular parellopiped shape( Fig : L - 7.1) within a large fluid region which is at rest. The forces acting on the element are body and surface forces. | | Body force

Think back to the key question. List two different fluids. How are their flow rates different? A3. Water and syrup flow rates are different because water has a high viscosity and syrup has a low viscosity rate. 7.3 Comparing Fluids (pg 157) Answer the questions below Q1. Andre and Kim have two fluids. Andre’s fluid flows much more easily than kim’s fluid.. (a) Which fluid has a faster flow rate? Andre’s (b) which fluid is more viscous? Kim’s Q2. Identify if each is

The history of the intravenous therapy is less than a century old. Yet‚ it is well known that medication could be injected directly into the vein as early as the 1600’s‚ because of the lack of scientific methods‚ original attempts to deliver IV fluids and drugs met with little success. Two world wars brought in the era of modern IV therapy. However‚ the greatest advance in drugs‚ equipment‚ and procedures has occurred in the past 25 years. The first intravenous injections were experimented with in
