As part of a processing of biofuels, water is pumped into a circular tank with a diameter Dt, as shown in Figure Q3. The flowrate into the tank is Q1 and the flowrate out is Q2. When the vessel is heated, water evaporates. The average velocity at which the vapour rises across the entire tank is vevap. You may assume that water has a density of pw, and vapour has a density of pu. Acceleration due to gravity is g. a) Find an expression for the rate of change of the mass of water in the tank. b) At time t = 0, the height of water in the tank is 10. Find an expression for the height as a function of time, h(t). c) An alarm is triggered when the pressure at the bottom of the tank exceeds palarm.

4. The circular tank of water is being filled from a pipe shown in figure below. The velocity of flowof water from the pipe is 10 ft/s. What will be the rate of rise ( in ft/s) of the water surface in the tank?
Consider the pipe system in the diagram below. Tank 1 is a closed tank and the pressure in tank 1 is kept constant at 200kPa. The water level in tank 1 is at 1.5m. You as an engineer are required to install a frictionless pipe between points A and B. Analyze the system and determine what is the maximum length of pipe would you recommend between A and B? The following conditions are applicable The gravitational acceleration is 9.81m/s2. The minimum required flow rate is 0.5m3/s. The atmospheric pressure is 85kPa. The water in the tank is saturated water with a density of 997kg/m3. The pipe inlet and outlet are both sharp-edged.

For a pumper truck pumping water to a fire, the back pressure is the additional pressure on the pump caused by the height of the nozzle. (Another way of thinking of back pressure is as the minimum pressure the pumper must produce in order to make water flow out the end of the nozzle.) Consider a pumper at street level pumping water through a hose to firefighters on the top of the ninth floor of a building. If each floor is 16 feet high, what is the head of water at the mouth of the nozzle?
Can you do Part D of this question. Parts A - C have already been done.
Water enters a fountain through a pipe with a cross-sectional area A₁ at a flowrate Q. The pressure in the inlet pipe is p₁. The water then leaves through a nozzle with a cross- sectional area A₂ and at an angle 0, as shown in Figure Q5. Both the inlet and the nozzle are at a height h₂, and the jet reaches a maximum height h3. You may assume that viscosity is negligible. a) Find the horizontal force on the block b) What is the horizontal-component (u₂), vertical component (v₂) and magnitude (V₂) of the velocity of the jet as it leaves the nozzle? c) What is the maximum height of the jet? You may assume that the horiztonal component of velocity is the same at every point in the jet. P₁ A₂. Ө h₂ h3 Figure Q5: Jet emitting from a fountain.

The water tower is closed but there is a section of air that is atmospheric pressure just above the water. The corsss ectional area at point 2 is 4.75 x 10 m. The cross sectional area fot the water tower is very large. What is the speed of the water coming out of the pipe at point 2? (density of water = kg/m³) 3.
