Ball Volume and surface Area

Image
Ball have surface area and volume formula that can define by the ball diameter or by ball radius, but to calculate the volume if the ball is not full calculate by other formula. If R = ball radius Then the surface area of ball can be calculated using the formula: 4 x π x R 2 Then the ball volume can be calculated by this formula: 4/3 x π x R 3 For example calculate this exercise: Count the volume of ball with radius of 3 cm. V = 4/3 x π x R 3 = 4/3 x 3.14 x 3 3 = 37.68 cm 3 How about if the ball contain of water but not full, say 1/3 of the ball height, count how much the ball volume? Can you count this? if you don't know yet, wait for my next blog.

Mathematical Language

--> In mathematical language, the propagation problem is known as an initial-value problem (Fig. Mat-2). Schematically, the problem is characterized by a differential equation plus an open region in which the equation holds. The solution of the differential equation must satisfy the initial conditions plus any “side” boundary conditions. Fig. Mat-1 The description of phenomena in a “continuous” medium such as a gas or a fluid often leads to partial differential equations. In particular, phenomena of “wave” propagation are described by a class of partial differential equations called “hyperbolic,” and these are essentially different in their properties from other classes such as those that describe equilibrium (“elliptic”) or diffusion and heat transfer (“parabolic”). Fig. Mat-2 Prototypes are: 1. Elliptic. Laplace ’s equation d 2 u/dx 2 + d 2 u/dy 2 = 0 Poisson’s equation d 2 u/dx 2 + d 2 u/dy 2 =g(x,y) These do not co...

Mathematic Principle

The basic problems of the sciences and engineering fall broadly into three categories: Steady state problems. In such problems the configuration of the system is to be determined. This solution does not change with time but continues indefinitely in the same pattern, hence the name “steady state.” Typical chemical engineering examples include steady temperature distributions in heat conduction, equilibrium in chemical reactions, and steady diffusion problems. Eigenvalue problems. These are extensions of equilibrium problems in which critical values of certain parameters are to be determined in addition to the corresponding steady-state configurations. The determination of eigenvalues may also arise in propagation problems. Typical chemical engineering problems include those in heat transfer and resonance in which certain boundary conditions are prescribed. Propagation problems. These problems are concerned with predicting the subsequent behavior of a system from a knowledge of the in...
