Density of water is 1000 kg/m3. Acceleration due to gravity g -10 m/s2 The water jet exiting from a stationary tank through a circular opening of diameter 300 mm impinges on a rigid wall as shown in the figure. Neglect all minor losses and assume the water level in the tank to remai The experienced by the wall kN Stationary rigid wall 6.2 m Circular opening of diameter 300 mm nstant. horizontal force is

A cylindrical steel rod, 0.01 m in diameter and o.2 m in length is first heated to 750 C and then immersed in a water bath at 100 C. The heat transfer coefficient is 250 W/m2-K. The density, specific heat and thermal conductivity of steel are r-7801 kg/m3, c 473 J/kg-K. and k 43 W/m-K, respectively. The time required for the rod reach 300 C is to seconds.
