2. A car is traveling on a highway at 28 m/s. a) What is the pressure at the bottom of a car's gas tank. that is a cube with side lengths of 0.5 meters? Assume the tank is full of gasoline with a denisty of 800 kg/m^3. b) How much pressure does a pump need to supply in order to draw gasloine from the bottom of the tank to the top of the tank? The velocity of the gasoline once it is pumped out of the tank should be 1 cm/s; the gas at the bottom of the tank is at rest. c) The gasoline from part b flows through a tube (cylinder) of radius lcm before entering a larger tube of radius 10cm. What will the velocity of the gasoline be in the larger tube? d) The tires on the car have an outer radius of 0.2 meters. How many complete rotations did the tires go through in one hour? Hint: Determine how far the car travels in one hour. e) How many hours can the car travel before running out of gas? f) During your journey. you hit a pothole and have to change your tire. You get your spare…
2) A compressor system which is controlled by starting-and-stopping is composed of a compressor with pumping capacity of 50 m3/min of free air and a receiver tank of 20 m3. The circuit demand is 25 m3/min of free air. No of start/stops is required to be 15 every hour. If the maximum line pressure is 8 bar gauge, what must be the low level pressure ?
An air compressor in Albuquerque with an 8-gallon tank is initially at atmospheric pressure (12.2psia, zero gauge pressure) and 60°F. The compressor is turned on and the tank gauge pressure iselevated to 120 psig. At the end of the pumping interval the air in the tank is at 120°F.a) How much air (lb mass) was added to the tank?b) What will the gauge pressure be in the tank after it cools back down to 60°F.
1. Using the Steam Tables, determine the heat absorbed by the boiler (KW) and Wsf when subcooled water at pressure = 5 Mpaa (subcooled by 64 deg C measured at the boiler inlet), is superheated to 100 degrees SH at the same pressure. Flow rate is at 10 cubic meters per minute. Ans.: a) Qa = b)Wsf= Hint: Use v at compressed water temp. at boiler inlet to convert to mass flow rate. Process is isobaric (Constant Pressure, where Q=m x AH).
