Question 2 (60 pts.): A liquid having a density of 1000 kg/m³ is continuously fed to a tank which is open to the atmosphere. A pump draws the liquid from the tank and pumps the liquid at steady state to a point 2 shown in figure below. The specific shaft work supplied to the pump is 10 kJ/kg. The pump is 100% efficient and the flow in the pipes and tank is inviscid. Please calculate the average velocity at the point 2 by making necessary and valid assumptions (1 J = 1 N.m and g=9.81 m/s²). Feed Stream $D_t=20$ m $Z1=3$ m 20 m $d_{pipe}=4$ mm $30^\circ$ Ignore the effect of this distance Z2 Steady-state Mechanical Energy Balance for incompressible flow (modified Bernoulli equation) $g(Z_2 - Z_1) + \left[\left(\frac{v_2^2}{2}\right) - \left(\frac{v_1^2}{2}\right)\right] + \left[\left(\frac{P_2}{\rho}\right) - \left(\frac{P_1}{\rho}\right)\right] - \bar{W}_s = 0$

Which of the following is not true regarding 1H NMR spectroscopy? Group of answer choices δ for a particular proton is independent of the magnetic field strength of the instrument used. a "downfield" peak appears at a lower value of δ "deshielding" leads to peaks at higher values of δ on a 300 MHz instrument, a proton that adsorbs irradiation at a frequency 900 Hz higher than the adsorption of TMS appears at δ 3 ppm.
