Find the net rate of heat transfer by radiation in watts from a skier standing in the shade, given the following. she is completely clothed in white (head to foot, including a ski mask), the clothes have an emissivity of 0.205 and a surface temperature of 11.4°c, the surroundings are at −17.0°c, and her surface area is 1.50 m2.

Avertical clean glass piezometer tube has an inside diameter of d = 1 mm and is used to measure pressure in a horizontal pipe carrying water as shown. due to pressure in the pipe, the water at 20c rises into the tube to a height h. if the water pressure in the pipe is p = 500 pa gauge, estimate the height h: (a) without considering surface tension (b) with surface tension (capillary) effects. the contact angle  can be assumed at 30 deg
