Question 1 (20 points) Convert the following quantities in the required unitss ?/ uired unit% / x ' bar 15 bar 1 bar a) 1.5 MPa-15. bar , 100 °F-.... K c) d) 150°C= e) 5.0106 cal..kWh R 40 MW= f) g) Btu/s Ibr 3000 dyn= 1.2 g/cm 3-.... kg/㡠h) 800 kg/m3 = Ibm/ft3 cm3/s i) j) 30 L/h = estion 2 (10 points) A dead-weight gauge is used to measure pressures up to 3500 atm. The piston diameter is 0.95 cm. What is the mass (in kg) of the weights required? Question 3 (15 points) The reading on a mercury manometer at 20 °C (open to the atmosphere at one end) is 28.71 inches. The local gravity is 32.186 f/s. The local atmospheric pressure is 101.29 kPa. The density of mercury at 20 °C is 13.495 g/cm3. What is the absolute pressure being measured, both in kPa and in psia? Question 4 (10 points) The gravity on Mars can be measured with a spring, which suspends a mass of 0.40 kg. On earth, where the local acceleration of gravity is 9.81 m/s, the spring extends 1.55 cm. When the instrument package is landed on Mars, the spring is extended only 0.59 cm. What is the acceleration of gravity on Mars?
