Question 1) A vertical hydraulic cylinder has a piston with a diameter of 75mm, if the ambient pressure is 80 kPa, determine the mass of the piston if the internal pressure is 1MPa.
Question 2) Saturated steam flows through a pipe of diameter 5 cm with a velocity of 45 m/s at 400kPa. If the mass flow rate of steam is 0.15 kg/s determine:
What is The specific volume in m3/kg?
What is the Volume flow rate m3/s?
Question 3) Air flows through a pipe of 60cm diameter with a velocity of 35 m/s. If the specific volume of the air is 0.5 m3/kg determine:
What is The flow?
What is the Mass flow?
Question 4) A cup of water (0.2kg) is at 20 degrees C. What height in meters is needed to produce sufficient Potential Energy to increase the temperature to 45 degrees C? (Assume no other losses).
Question 5) Pressure in a piston system is at 140 kPa and a volume of 0.5m3 if the volume is increased to 0.8m3 what is the new pressure?
Question 6) A volume of 0.0125 m3 at a temperature of 140 degrees C and pressure at 75kPa has the temperature increased by 150 degrees F. What is the new volume?
