Saturate the powdered seed material with lighter fluid, naphtha or ligroine. When completely saturated, it should have the consistency of soup.

Products with a high percentage of solvents, such as oil-based paints, paint removers, fuels, lighter fluids, furniture polishes, and some pesticides can cause potentially fatal pneumonia if aspirated into the lungs as a result of accidental ingestion. If used in an unventilated space, they can also cause symptoms of acute intoxication, including dizziness, nausea, and in some cases nerve damage or other effects. 

Two-fluid U tube (Fig. 10-7). This is a highly sensitive device for measuring small gas heads. Let A be the cross-sectional area of each of the reservoirs and a that of the tube forming the U let pi be the density of the lighter fluid and p2 that of the heavier fluid and if R is the reading and flo its value with zero pressure difference, then the pressure difference is...

Results The combination of water and soap mixed easily with the kerosene, lighter fluid, and magnesium sulfate. The oils, however, did not mix with water or with water and soap together. No matter how hard you shook the mixture, the oils always separated when you allowed the mixture to stand. In other words, the oils did not dissolve in water. 

We used to make a different version of Joe Brown s Fire Ball Cannon. Ours was hand-held. You squirt the lighter fluid into the hole at the bottom and then whip the taped together cans up and down in a stiff-arm motion as though you were going to beat the ground with it. You then take a match which is lit and hold it by the hole - boom WHEEl... 

The characteristics of heat transfer through a horizontal enclosure depend ou whether the hotter plate is at the top or at the bottom, as shown in Fig. 9-22. When the hotter plate is at the top, no convection currents develop in the enclosure, since Ihe lighter fluid is always on top of the heavier fluid. Heat transfer in tlris case is by pure conduction, and we have Nu - 1. When the hotter plate is at the bottom, the heavier fluid will be on top of the lighter fluid, and there will be a tendency for Ihe lighter fluid to topple the heavier fluid and rise to the top, where it comes in contact with the cooler plate and cools down. Until that happens, however, heat transfer is still by pure couduc-tion and Nu — I. When Ra > 1708, the buoyant force overcomes the fluid resistance and initiates natural convection currents, which are observed to be in the form of hexagonal cells called BSnard cells. For Ra > 3 X 10, the cells break down and the fluid motion becomes turbulent. 

Rapid Release Sometimes energy is released rapidly. For example, charcoal lighter fluid combines with oxygen in the air and produces enough heat to ignite a charcoal fire within a few minutes. 

Pour 1 ml of NaBr solution into a small test tube, and add three drops of chlorine water. Stir the solution with the tip of a microtip pipet. Add 1 ml of lighter fluid. Draw the entire mixture into the microtip pipet. Squeeze the pipet bulb, expelling the mixture back into the test tube. Repeat this step several times so that the liquids are thoroughly mixed. (CAUTION Use care when handling chlorine water.)... 

Using another test tube and microtip pipet, repeat procedures 3 and 4 with 1 ml of an Nal solution, chlorine water, and lighter fluid. 

Inject a 5 pL sample of any of the following lighter fluid, lantern fluid, or kerosene. Flush the syringe several times with the new liquid before you inject it. IMMEDIATELY GO TO STEP 44 AFTER THE INJECTION. 

Spatial fluid density variations are frequently inherited from the filling history of the reservoir. The initial fluids expelled from a source rock are relatively dense liquids. As a source rock becomes more thermally mature, it expels progressively lighter fluids and eventually gases. When such fluids fill a reservoir, and fill and spill from compartment to compartment within a reservoir, each part of the reservoir can end up with different proportions of fluids of different maturity and density. Field observations show that the segment of the reservoir closest to the source kitchen has often received the latest, lowest density charge. Those areas farthest away from the source kitchen may contain earlier denser fluids that have filled and spilled to their current location. 

Gradients in surface tension can also lead to an instability, with subsequent cellular-type flows. These unstable flows are similar in character to the unstable convection that results when a density gradient is parallel to, but opposite, a body force, such as gravity. In this case the fluid is in unstable equilibrium with the heavier fluid on top of the lighter fluid. When a. critical...
