The hydraulic motor drive was a piston-type, nine-cylinder, fixed-stroke imit and provided a rated 40 hp at 6000 rpm with 25-gpm oil at 3000 psi. This accommodated a high-output pump performance of 100 psi shutoff head at 8500 rpm, and 1510 gpm at... 

Several designs have evolved, many with horizontal axes (i.e. both ends closed) with the outer cylinder rotating and the inner cylinder fixed, which provides best hydrodynamic stability. Some horizontal-axis Couette flocculators are flow-through designs, even with a tapered gap to provide taper flocculation However, horizontal-axis apparatuses suffer from end effects which cause secondary circulation, so only a limited central zone (about one quarter of the length) is in defined laminar flow. 

Both Eqs. (11.1) and (11.2) account for the effect of transverse strain on plastic strain intensity factor characterized by the modified Poisson s ratio, V. In Eq. (11.1), this is accounted for by the ratio Sy/Sa, whereas in Eq. (11.2) the ratio Eg/E serves the same purpose as will be shown later. The modified Poisson s ratio in each case is intended to account for the different transverse contraction in the elastic-plastic condition as compared to the assumed elastic condition. Therefore this effect is primarily associated with the differences in variation in volume without any consideration given to the nonlinear stress-strain relationship in plasticity. Instead the approaches are based on an equation analogous to Hooke s law as obtained by Nadai. Gonyea uses expression (rule) due to Neuber to estimate the strain concentration effects through a correction factor, K, for various notches (characterized by the elastic stress concentration factor, Kj). Moulin and Roche obtain the same factor for a biaxial situation involving thermal shock problem and present a design curve for K, for alloy steels as a function of equivalent strain range. Similar results were obtained by Houtman for thermal shock in plates and cylinders and for cylinders fixed to a wall, which were discussed by Nickell. The problem of Poisson s effect in plasticity has been discussed in detail by Severud. Hubei... 

The circular cylindrical rheometer only applies stresses to make the inner cylinder rotate and keep the outer cylinder fixed. No force is exerted along the Oz axis, and consequently, tniRi) = 0. The torque exerted on the entire contact surface of the...

A number of concentric cylinder instruments rotate the outer cylinder f2o and hold the inner cylinder fixed. For this case we can just replace with 2o in eq. 5.3.24 and S.3.2S. 

It is of great advantage, however, to have available a second cylinder similar to, but much shorter than, C, and of wider internal bore. When the pellet has been formed inside C, the plunger S is released and the shorter cylinder inserted between C and the base B. The plunger S is again screwed down, and the pellet is thus slowly forced out of C into the shorter cylinder below. In this way the pellet, even if originally firmly fixed in C, can be removed without risk of fracture... 

Variations in the Force Due to Gravity. The mass of an object is the quantity of matter ia the object. It is a fundamental quantity that is fixed, and does not change with time, temperature, location, etc. The standard for mass is a platinum—iridium cylinder, called the International Kilogram, maintained at the International Bureau of Weights and Measures, ia Snvres, France. The mass of this cylinder is 1 kg by definition (9). AH national mass standards are traceable to this artifact standard.

Price. The 1993 U.S. price for fluorine in cylinders was 109/kg for 2.2 kg and 260/kg for 0.7 kg cylinders. The price in large volumes is determined by (/) the price of hydrofluoric acid (2) power costs, ca 4.5 kWh electricity is required for each kilogram of fluorine produced (J) labor costs (4) costs to maintain and rebuild cells and (5) amortization of fixed capital. Fluorine production is highly capital intense. In addition, purification, compression, packaging, and distribution in cylinders increase the cost significantly.

For gas temperatures in excess of 380°C, experienced manufacturers often mount the adjustable guide vanes in special ceramic bearings. The shaft end of each blade is fixed to a lever, which is connected to a hinge-mounted adjusting cylinder. Axial movements of the cylinder open or close the blading.

As the piston starts its suction stroke, the gas that remains in the cylinder in the fixed and added clearance areas expands until the pressure in the cylinder is equal to the pressure in the line outside of the cylinder. The greater the clearance, the longer it takes for the suction valves to open and the less new gas enters the cylinder. Therefore, less gas will be compressed as cylinder clearance is increased. 

Variable clearance that can be changed very readily can be built into the cylinder. Figure 11-19 is an example of a fixed volume clearance pocket mounted on the cylinder. This type is separated from the cylinder by a valve that can be opened and closed from the outside. 

Fixed clearance can also be added to the outer end of the cylinder by adding a fabricated clearance bottle with the desired volume. To change the performance of the cylinder the clearance can be changed by shutting down the compressor, unbolting one bottle, and installing another bottle with a different volume. It is very easy in that respect to add clearance and subtract clearance from a cylinder if the cylinder is set up to receive clearance bottles.
