(b) Perform a perspective projection onto the z-plane of the unit cube where center of projection is at (-10, -10, -10). [2X3=6]
2. Water with density \(\rho\) flows from tank 1 to tank 2. Find the water height \(h_1\) in tank 1 shown in Fig 2 so that the water inlet and outlet for tank 2 remains the same (steady-state). Assume the tank is very large for both tank 1 and tank 2. (adopted from Muson et al. P3.48)
Question 2 $P_{312} = 460$ $P_{320} = -260$ 2. $x = 1$ $x = 6$ Find E :
An atmospheric storage tank, with a minimum liquid level of 300 mm, is elevated on a 1 m high platform. A pump, which handles 100,000 kg/hr flow of water at 25 degrees Celsius, is connected to the tank via a 6-inch ID suction line, 20 m long. The suction nozzle of this pump is 0.4 m above ground level. Draw an illustration of the system and calculate the NPSH for this pump.
Given a degree sequence d1, d2, d3, ..., dn such that 0 < di < n for each i and the sum of the degrees d1 + d2 + d3 + ... + dn = 2n - 2, prove that there must exist a tree whose vertices have these degrees. (Hint: Use Induction)
