Question • Convert the following: • 7 ft to inches • 60 miles/hr to ft/sec • 2000 ft 3 to gallons • Given mass = 68 kg, and Area = 300 cm 2. • Find the pressure in N/m 2. 5

Question • The temperature of ambient air in a certain location is measured to be -40 0 C. Express this temperature in the following units: • Fahrenheit • Kelvin • Rankine 6

Questions • Freshwater and seawater flowing in parallel horizontal pipelines are connected to each other by a double U-tube manometer. Determine the pressure difference between the two pipelines. Take the density of seawater at that location to be ρ = 1035 kg/m 3. Can the air column be ignored in the analysis? • Repeat the problem by replacing the air with oil whose specific gravity is 0. 72 7

• A hydraulic lift is to used to lift a 2500 kg weight by putting a weight of 25 kg on a piston with a diameter of 10 cm. Determine the diameter of the piston on which the weight is to be placed. 8

• Calculate the absolute pressure, P 1 of the manometer shown in k. Pa. The local atmospheric pressure is 758 mmhg. • Consider the same manometer. If the specific weight of fluid A is 100 k. N/m 3, what is the absolute pressure, in k. Pa, indicated by the manometer when the local atmospheric pressure is 90 k. Pa? 9
