- The surface tension of mercury and water at 60°C are 0.47N/m and 0.0662 N/m. respectively. What capillary height (in mm) will occur in the water when it is in contact with air in a glass tube of radius 0.355 mm? Use 130° for mercury and O° for waterBased on the expression dp/dz = -pg, at what elevation is the absolute pressure 70% of the pressure at sea level? Take g to be a constant, assume changes in the atmosphere's state with elevation to be polytropic with n = 1.228, and take the temperature and pressure of the atmosphere at sea level to be 25.5°C and 0.92 atm. a. The elevation is b. The density of the air at sea level is kilometres. kg/m³.2.19 Determine the change in the kinematic viscosity of air that is heated from 10°C to 70°C. Assume standard atmospheric pressure.

- Question 2* A thin flat plate is immersed in a fluid stream 20 m/s. Estimate the distance x from the leading edge at which the boundary layer will be I mm or 10 cm for (a) air and (b) water at normal room temperature and pressure. (For air 0.0615 m, 6.47 m; for water 0.044 m, 9.52 m)3. What is the equivalent height in meters of glycerin (sg = 1.26) for an absolute pressure of 5 atm when barometer reads 800 mm Hg. Also find the equivalent height of oil (sg = 0.8) in inches.How did you determine the mean temperature of water to be 304 K?
