Question 1 You have available a 550 W pump with 70% efficiency. Is it possible to use this pump to transfer 10 m$^3$/h of a liquid through a 4.7 cm inside diameter pipe from one open tank to another, if the liquid is discharged at a point 10 m above the liquid level in the suction tank and the total friction losses are 50 J/kg? The density and the viscosity of the liquid are 1050 kg/m$^3$ and 2cP, respectively.

Exercise 3 - RBC model (4 points); Consider the following simple RBC model. Preferences are given by $\infty$ $E_0 \sum_{t=0} \beta^t [b c_t^{1-\mu} + (1 - b) l_t^{1-\mu}]; \quad 0 < \beta < 1$ where $l = 1 - n$ is leisure and production technology is given by $y_t = e^{z_t} k_t^\alpha n_t^{1-\alpha}$ and the resource constraint $c_t + k_{t+1} - (1 - \delta) k_t = y_t$ a) Set up the social planner's problem for the economy and derive the first order conditions. b) Instead of a social planner, assume there are households that maximize utility and firms that maximize profit. Households and firms interact in competitive markets. c) For a given value of consumption and wage, how does the increase in b affect the labor supply curves?
