During your experiment, you collected 2 data points in the fully submerged case. For the purposes of answering the post-lab, these are as follows: Mass Level of Water Data ID m(g) h(mm) Full 1 400 96 Full 2 450 90 Give your answers with 3 significant figures. Answers within 3% are considered correct. The following standard assumptions are made: Density of water = 1000.0 kg/m3 Acceleration due to Gravity = 9.81 m/s2 Moments are calculated about the centre of rotation "0" (see Figure 2 in the lab notebook). Q1a. What is the experimentally measured Moment (Mexn) for Full 1? Мехp_1 %3 N. m Q1b. What is the theoretical Moment (Miheoryful) for Full 1? Mtheory_1 = N. m Q2a. What is the experimentally measured Moment (Mexp) for Full 2? Mexp_2 = N. m Q2b. What is the theoretical Moment (Miheoryfuid for Full 2? Mtheon ?:

The discharge in a rectangular channel is given as Q = V*W*H, where V is the measured velocity, W is the channel width, and H is the depth of water. The table below gives the average of many measurements of each of the terms and the associated standard uncertainty. What is the discharge in this channel and its uncertainty?

Question B2 As shown in Figure B2, a cylindrical steel structure (density pb = 8000 kg/m³) loosely sits vertically on a flat concrete slab that is fixed at the bottom of the riverbed and in parallel to the river stream. The diameter and length of the cylindrical steel structure, which is fully immersed in the river stream, are 1 m and 6 m, respectively. The properties of water are given as density p = 1000 kg/m³ and viscosity µ = 1.0x103 N.s/m?, respectively. The drag coefficient of the cylindrical steel structure can be taken as 0.5. It is assumed that i) the flow of river stream is steady; i) the ground effect around due to the slab on the river stream is negligible; ii) the acceleration due to gravity, g. can be taken as 10 m/s?. Determine the minimal speed of river stream, V, at which the cylindrical steel structure can be tipped over. V H=6m D=Im Concrete slab River bed Figure B2
