QUESTION 3 Figure below indicated that a plug with cone shape used to plugged a hole of 45 cm radius at one side of a tank that containing X fluid (SG-0.8). The cone is 1.5 m height and I.I m bottom diameter. Depth of cone center point to the surface liquid is 10m. a) Draw the distribution of pressure onto the plug b) Determine the force acts onto the plug Cone 10 m QUESTION 4 Figure below shows a water...

Still water of some depth initially at 37°C has its surface raised to 100°C (6 and maintained at this level. Determine the depth at which the temperature will reach 48°C after 10 seconds. Also find the heat flow during this time into the water. If the surface temperature only was raised to 50°C determine .these quantities.(Thermal diffusivity) a = 1.595 x 10^-7 m2/s; k = 0.656 W/mK

When the hydrofoil shown was tested, the minimum pressure on the surface of the foil was found to be 80 kPa absolute when the foil was submerged 1.9 m and towed at a speed of 7 m/s. At the same depth, at what speed will cavitation first occur? Assume irrotational flow for both cases and T = 10 °C. Water = 10°C (50°F) (a) What is the absolute pressure of the atmosphere? kPa (b) What is the specific weight of...
