When a fluid flows over a surface, the shear stresS I (N/m) at the surface is given by the expression du dy surface where u is the viscosity (N-s/m), u is the velocity parallel to the surface (m/s), and y is the distance normal to the surface (cm). Measurements of the velocity of an air stream flowing above a surface are made with an LDV (laser-Doppler-Velocimeter). The values given below were obtained. y u y и 0.0 0.00 2.0 88.89 1.0 55.56 3.0 100.00 At the local temperature, u = 0.00024 N-s/m. In four decimal places, calculate du/dy at the surface using all the points.
An underground storage tank (volume =1 m') spills its contents of 1 kg of TCE in a 10 m thick sand aquifer. the seepage velocity is 1 m/day in the x direction. the longitudinal dispersivity is Im, transverse and vertical dispersivities are 0.1 m. A) calculate the maximum concentration at distance x= 500m B) if the contaminant was uniformly spilled over the 10m thickness of the aquifer what is the m concentrations at x= 500m with longitudinal dispersivity is Im, transverse dispersivity is 0.1 m and vertical dispersivity=0
Calculate (a) the specific volume, (b) the enthalpy, and (c) the absolute humidity of the air at 40 ° C and the relative humidity of 49%, at a barometric pressure of 770 mm Hg. a) specific volume = .... m³ / kg b) enthalpy = ... (kj / kg air) c) absolute humidity = .... (kg water / kg air)
When a chalk is broken into dust-like particles, the particles take a long time to settle down to the ground when compared to the original chalk although the density of the chalk and the viscosity of air remain the same. The reasons for this are: (i) (ii) (i) (ii) The Reynolds number is very low due to reduced length scale of the dust. The dust particle is much lighter than the chalk. The viscous force is a surface force proportional to the length square while the gravitational force is a body force proportional to the length cube. At very small length scale, length square is much larger than length cube. (iii) (A) (B) The largest animal is found in sea as it requires no energy to support its weight by using hydrostatic principle. However bird has to support its own weight by using Bernoulli principle to create pressure difference while in flight. Bird cannot be very large and there are also fewer species of large bird than small bird. The reasons are: There is less food in the air…
