Aparticular slurry is a nonnewtonian shear-thinning fluid, subject to the "power law", i. e., =m ||·n, with n = 0.8 and m = 80 cp s(n-1). we desire to pump the slurry a distance of 12 m through a smooth pipe of diameter 8 cm at a rate of 12 kg/s. the fluid has density of 1100 kg/m3. compute the required pressure drop to achieve this flow. give your answer in kpa.

Ariver flows from north to south at 8 km/h. a boat is to cross this river from west to east at a speed of 20 km/h (speed of the boat with respect to the earth/ground). at what angle (in degrees) must the boat be pointed upstream such that it will proceed directly across the river (hint: find the speed of the boat with respect to water/river)? a 288 b. 21.8 c. 326 d. 30.2
