WebThe coefficient of viscosity of water is 10-3 Pa s. After some time the flow rate is increased to 3 L/min. Characterise the flow for both the flow rates. (5 marks) Ans. Let the speed of the flow be v and the diameter of the tap be d = 1.25 cm. The volume of … WebExample - water is a liquid where the volumetric expansion coefficient changes a lot with temperature. Water has its highest density and smallest volume at 4 o C (39.2 o F). The volumetric coefficient for water is negative below 4 o C and indicates that the a volume decreases when temperature moves from 0 o C (32 o F) to 4 o C. WebPermeability coefficient is a very important factor for shield machine type selection. Usually, when the permeability coefficient of the stratum is lower than 10 −7 m/s, an EPB shield can be selected. When the permeability coefficient of the stratum is between 10 −7 and 10 −4 m/s, either an EPB or slurry shield can be selected. When the permeability … mouse trust wireless istruzioni
