Page 113 - FIG. 35. buoyant force exerted upon any body immersed in a fluid (Fig. 35) is equal to the weight of the fluid displaced by the body, and acts through the center of gravity of the body.
Page 470 - ... is the ratio of the specific heat at constant pressure to the specific heat at constant volume, is a constant.
Page 2 - Mass of fluid Mass of fluid p Volume Thus specific volume is the reciprocal of mass density. It is expressed as m3/kg. It is commonly applied to gases. 1.2.4 Specific Gravity. Specific gravity is defined as the ratio of the weight density (or density) of a fluid to the weight density (or density) of a standard fluid. For liquids, the standard fluid is taken water and for gases, the standard fluid is taken air. Specific gravity is also called relative density. It is dimensionless quantity and is denoted...
Page 275 - ... the open channel. The notch is of small size while the weir is of a bigger size. The notch is generally made of metallic plate while weir is made of concrete or masonary structure.
Page 3 - Viscosity is defined as the property of a fluid which offers resistance to the movement of one layer of fluid over another adjacent layer of the fluid. When two layers of a fluid, a distance 'dy' apart, move one over the other at different velocities, say u and u + du as shown in Fig.
Page 82 - A square aperture in the vertical side of a tank has one diagonal vertical and is completely covered by a plane plate hinged along one of the upper sides of the aperture. The diagonals of the aperture are 2 m long and the tank contains a liquid of relative density 1-15.
Page 125 - In case of floating body, the weight of the body is equal to the weight of liquid displaced.
Page 163 - It is defined as a scalar function of space and time such that its negative derivative with respect to any direction gives the fluid velocity in that direction.
Page 413 - Lg in equation (4.46), ie , —^ is neglected. If the velocity of the body is comparable with velocity of sound, the effect due to compressibility is to be considered. But if the ratio of the velocity of the body to the velocity of the sound is less than 0.3, the force exerted by the fluid on the body due to compressibility is negligible. Hence the non-dimensional term in equation (4.46) containing K can be neglected.
