Replication of Air pressure experiment Find an air filled ball that has an air input that will allow you to increase or decrease the air pressure. I used a rubber basketball but a leather basketball would have also worked. The smaller the ball, the harder it is going to be to see the differences in bounce height. Use an air pump and an air pressure gauge to put air in the ball and to measure the air pressure in the ball. Make sure you adjust the air pressure between bounces and measure and

For a process to be adequately controlled and manipulated, the variable of interest in the process (e.g. Temperature, Pressure or Flow) often called the Process Variable (PV) needs to be measured by a sensor which converts the measurement into a suitable signal format (4 – 20mA or digital) and then transmit it to a controller which makes the control decision and finally acts on a final control element in the control loop. What does this signal transmission is referred to as a transmitter. The schematic

Question# 1 The geocentric view of the universe was long since developed in ancient Greece by an astronomer named Claudius Ptolemy (AD 90- 168). Ptolemy believed that the sun, stars and other planets revolved around the earth. The idea of “Geocentric” means everything revolves around Earth. It wasn’t long until Nicolaus Copernicus (1473-1543), an astronomer from Poland came up with a new theory that the solar system actually revolved around the sun. He invented the idea of a solar system. Revolutions

with appropriate labels. ii. Determine the atmospheric air pressure, in bar. iii. Calculate the absolute pressure of the air in the vessel, in kPa. (Ans: 1 bar; 80 kPa) 2. A gas is contained in a vertical, frictionless piston-cylinder device, as shown in Figure 1.1. The piston has a mass of 4 kg and cross sectional area of 35 cm2. A compressed spring above the piston exerts a force of 60 N on the piston. If the atmospheric pressure is 95 kPa, determine the absolute pressure
