Question 4

(a) Refer to Newtons law of viscosity and fluid flow patterns, state the differences between;

(i) Newtonian and non-Newtonian fluids. . [2marks]

(ii) Uniform and steady flows. [2marks]

(b) Water is flowing out from a water tank as shown in Figure 2. Determine the velocity and mass flow rate of the water with values given in the figure below, (g = 9.81 m/s; water = 1,000 kg/m3 ).

(b) Water is flowing out from a water tank as shown in Figure 2. Determine the velocity and mass flow rate of the water with values given in the figure below, (g = 9.81 m/s; Pwater = 1,000 kg/m3). Air mengalir keluar dari satu tangki air seperti ditunjukkan dalam Rajah 2. Tentukan halaju dan kadar aliran jisim air dengan nilai diberikan dalam rajah di bawah, (g = 9.81 m/s; pair = 1,000 kg/m3).
