subject Q5: A 100-ft³/s water jet is moving in the positivex-direction at 20 ft/s. The stream hits a stationarysplitter, such that half of the flow is divertedupward at 45° and the other half is directed 100 ft³/sdownward, and both streams have a final speed of20 ft/s as shown in Figure H3.5. Disregardinggravitational effects, determine the x- and z-components of the force required to hold thesplitter in place against the water force. Take thedensity of water to be 62.4 lbm/ft³.Answer: FR-X-1140 lbf, FR-=0 lbf20 ft/s45°FRFRE450Figure: H3.5

Make a sketch to indicate (a) the boundary of the system at time i = 20.1 s, (b) the fluid that left the control volume during that 0.1-s interval, and (c) the fluid that entered the control volume during that time interval.
Hello, I know the right answer, I just can't seem to get there. Any helps is greatly appreciated!
Q3.2. Air enters the lungs through a circular channel with a diameter of 3 cm and a velocity of 150 cm/s and a density of 1.25 kg/m . Air leaves the lungs through the same opening at a velocity of 120 cm/s and a density equal to that of the air within the lungs, which has decreased its net density, due to the lower density air entering the lungs. At the initial conditions the air within the lungs has a density of 1.4 kg/m3, with a total volume of 6 L. Find the aggregate rate of change of the density of air in the lung assuming that your time step includes one inhale and one exhale (takes 15 s) and that there is no change in the lung volume over this time.
4.71 Water enters a 1.5 m wide, 0.3 m deep channel as shown in Fig. P4.71. Across the inlet the water velocity is 1.8 m/s in the center portion of the channel and 0.3 m/s in the remainder of it. Farther downstream the water flows at a uniform 0.6 m/s velocity across the entire channel. The fixed control volume ABCD coincides with the system at time t = 0. Make a sketch to indicate (a) the system at time ! = 0.5 s and (b) the fluid that has entered and exited the control volume in that time period.

could you please help me calculate the maximum height of the jet , Hj in metres please
PLEASE FOLLOW THE INSTRUCTION AND TRY TO ANSWER CORREVTLY. PLEASE ANSWER QUICKLY . THANKS
A water jet with a flow rate of 2.83 m3 / s is traveling at 6 m / s in the positive x direction. The cost of the current striking a stationary splitter is correct about a 45 aç angle, other company are deflected downwards by the same angle and the final velocities of the two streams are 6 m / s. By neglecting the gravity, the separator is in place against the force applied by the water. calculate the x- and z- power of what is required to hold it. For water ? = 1.184 kg / m3
Q3. A pump draws water through a 20-cm suction pipe and discharges it through a 10- cm pipe in which the velocity is 3 m/s (Fig. 3). The 10-cm pipe discharges horizontally into air at point C. To what height h above the water surface at A can the water be raised if 35 kW is delivered to the pump? Assume the head loss in the pipe between A and C is equal to 2V²J/2g. Pump Water Fig. 3
Complete Solution please, thanks. 3. A vertical circular stack 30 m high converges uniformly from a diameter of 6 m at the bottom and 4.5 m at the top. Gas with a unit weight of 0.12 N per cubic meter enters the bottom of the tank with a uniform velocity of-assume values with decimals between 3 to 4 m per second- enters the stack. The unit weight increases by 7.5 percent every 2 meters. Find the velocity of flow at every 5 meters along the stack.
