change of mass within system Writing the mass balance expression for a stirred tank Consider a well-mixed tank of liquid (figure 1). The inlet stream flow is Fin (m3/s) with density ρin (kg/m3). The volume of the liquid in the tank is V (m3) with constant density ρ (kg/m3). The flow leaving the tank is F (m3/s) with liquid density ρ (kg/m3). Table 1 summarises each term that appears in the mass balance. Figure 1. Mixed Tank of Liquid Rate of mass flow in inlet flowrate × density Rate of

Abstract This experiment of the friction loss along a smooth pipe shows that there are existence of laminar and transitional flows as stated in Graph 2.0 and Graph 2.1. It is proven that the higher velocity along the smooth bore pipe‚ the higher is the head loss of water. As shown in Table 3.0‚ when the Reynolds’ number increases‚ the value of pipe coefficient friction‚ f decreases along the decreasing stead laminar line. On top of that‚ there are energy loss from the water to the surface of the

Introduction Concrete mixtures can be designed to provide a wide range of mechanical and durability properties to meet the design requirements of a structure. The compressive strength of concrete is the most common performances measure used by engineer in designing buildings and other structures. The compressive strength is measured by breaking concrete specimen in a compression-testing machine. The compressive strength is calculated from the failure load divided by the cross-sectional area resisting
