4.2-4. Energy Balance on a Heat Exchanger and a Pump. Water at 93.3°C is being pumped from a large storage tank at 1 atm abs at a rate of 0.189 m³/min by a pump. The motor that drives the pump supplies energy to the pump at the rate of 1.49 kW. The water is pumped through a heat exchanger, where it gives up 704 kW of heat and is then delivered to a large open storage tank at an elevation of 15.24 m above the first tank. What is the final temperature of the water to the second tank? Also, what is the gain in enthalpy of the water due to the work input? (Hint: Be sure to use the steam tables for the enthalpy of the water. Neglect any kinetic-energy changes but not potential-energy changes.) Ans. t₂ = 38.2°C, work input gain = 0.491 kJ/kg

Q2 (12 points) The following do not define inner products on the indicated vector space. Explain why. a) V = \mathbb{R}^2, \langle x, y \rangle = x_1x_2y_1y_2, where $x = (x_1, x_2)$, $y = (y_1, y_2)$ b) V = P_3, \langle p(x), q(x) \rangle = p(1)q(1) for p(x), q(x) \in P_3 (Here, p(1) just means set x = 1 in p(x). For example, if p(x) = x^3 - 4x + 1 then p(1) = 1 - 4 + 1 = -2.) c) V = M_{2,2}, \langle A, B \rangle = det(AB)

Let a, b ? N, with b? a. Assume that $\frac{a^2 + b^2}{ab + 1}$ = k is an integer. The purpose of this problem is to show that k is square. The method here is reduction (or the method of descent). Let (a', b') ? N², with b' ? a' be a minimal postive integer solution to $\frac{x^2 + y^2}{xy + 1}$ = k, x, y ? N; here the minimal is among all values of x + y. Let b* = ka' - b'.
