Question: Suppose a hiker falls into a crack in a glacier while mountain climbing. Assume the ice moves as a Newtonian fluid with viscosity = 250 x 106 CP and sp. gr. = 0.97 and assume the glacier is 15-m deep and is on a slope that falls 1.5 m every 1850 rn. In order to determine how long before the professor appears at the bottom of the glacier a model is to be constructed
On a cool morning, when the temperature is 15deg Celsius, you measure the pressure in your car tires to be 30 psi. After driving 20 mi on the freeway, temperature of your tires is 45 deg Celsius. What pressure will your tire gauge now show.
