Question P3.186 The horizontal pump in Fig. P3.186 discharges 20°C. water at 57 m /h. Neglecting losses, what power in kW is delivered to the water by the pump? 120 kPa 400 kPa Pump P3.186 D = 9 cm D2 = 3 cm

You are designing the section of a roller coaster ride shown in the figure. Previous sections of the ride give the train a speed of 12.5 m/s at the top of the incline, which is h = 37.1 m above the ground. As any good engineer would, you begin your design with safety in mind. Your local government's safety regulations state that the riders' centripetal acceleration should be no more than n = 1.93 g at the top of the hump and no more than N = 5.53 g at the bottom of the loop. For this initial phase of your design, you decide to ignore the effects of friction and air resistance. (Figure not to scale) h Roop R hump What is the minimum radius Rhump you can use for the semi-circular hump? Rhump m What is the minimum radius Rioop you can use for the vertical loop? Roop = m

Drop down choices for both a. and b. -cost-push inflation -a change in inflation expectations -demand-pull inflation The Phillips Curve and Inflation - End of Chapter Problem For each scenario, determine whether inflation expectations, demand-pull inflation, or cost-push inflation will change. a. A rapid influx of foreign investment causes the output gap to become more positive. This gives rise to b. The president unexpectedly announces a tariff on aluminum and steel. This causes

CIRCLE ALL ANSWERS AND PROVIDE UNITS 1. (20 points) Mohr's Circle and Stress Elements Oy An element in plane stress (shown above) is subjected to stresses Ox - 70 MPa, Oy, and Txy - 50 MPa. Using the Mohr's Circle equations, determine the following: a principal stresses, b. the maximum shear stress, C. the principal angle, d. If one of the principal stresses is negative, what does a negative stress mean? **Using just proper equations is acceptable, but Extra Credit will be given if Mohr's Circle is drawn out.

You make a swimming pool 3.92 M in magnesium acetate, Mg(CH3COO)2 hoping to keep it from freezing during the winter. Its density is 1.23 g/ml. What will its normal freezing point be? Give your final answer (remember, you're looking for the new normal freezing point) to 1 decimal place (just to keep CuLearn happy) Put C for your unit (I don't know how to find the degree sign for answers...) Kf(H2O) = 1.86 °C/m
