Consider an enclosure consisting of a hemisphere of diameter D and a flat surface of the same diameter Determine the relevant view factors. D/2

1.23.* The Reynolds number, discussed in Chap. 6, is defined for a pipe as (velocity . diameter density) / viscosity. What is the Reynolds number for water flowing at 10 ft /s in a pipe with a diameter of 6 in? What are its dimensions?

Calculate the viscosity of oxygen at 350 K and 1 atm pressure using equation 7.12 on page 90 of the text (also found in the PowerPoint slides).and compare with the value in Appendix I.

Determine the magnitude of the force on the bottom plate if the length L = 5 cm and the width W = 2 cm(dynes; 2 significant figures; do not use scientific notation)

Show p = pgh and show handling of units

AU-tube manometer contains oil (50 Ibf/ft), mercury (849 847 Ibf/ft) and water (62.4 Ibf/ft). For the heights shown/indicated what is the pressure differential between pipes A and B, or APAB? Oil to 3 in. Water 12 in. Mercury What is APAR (in Ibft?)?

True or false: Osmotic pressure can be explained by the difference in fugacities

Determine the pressure difference in [Pa] between points A and B for the manometer shown in Figure H.
