During an accident, a heavy vehicle's tyre with inner diameter 0.8m and outer diameter 1.2m is immersed in water with its plane making an angle of 45 degree with the horizontal free surface of water. The center of the inner and outer diameters of tyre is located at 1.625m below the free surface. What will be the total pressure force on the face of the tyre?

The mass flow rate of the fluid remains constant in all steady flow process. a)- true b)- false

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

Water at 55c flows across a flat plate whose surface temperature is held constant at 95c. if the temperature gradient at the plate's surface for a given value of x is 18 c/mm, find a) local heat transfer coefficient. b) heat flux
