can you please state the correct and incorrect statements based on its topic.
Saturation Curve/Line
I. For every saturation temperature, there is always a corresponding saturation pressure
II. Inside the Saturation Curve, the quality of steam can be less than 100%
III. If a point is located outside of the Saturation Curve, it can only be a superheated vapor
Please help me. (45 mins. left), I'll give a thumbs up)
Given the ultimate/gravimetric analysis of coal as follows:
C=81.95%, H2 = 4.63%, S=0.96%, N2=1.3%, O2=5.75%, Ash=6.09%, Moisture = 3.05%
Using ash and moisture free analysis. Determine the; mass of the wet flue gas
how do civil contractor check that they have reached 95% of the maximum dry density (proctor test) onsite ?

- Which of the following statements about a fuel volume test is not true? a. This test measures the flow rate of the pump and can help isolate fuel system restrictions or weak pumps. b. The test is conducted by collecting the fuel dispensed by the certain during a period of time, normally 5 seconds. c. The flow of fuel into the container should be smooth and continuous with no signs of air bubbles. d. Poor results may indicate a bad pump or restrictions in the delivery system.arrow_forwardWhat are three instruments that a flue-gas analysis kit might contain?arrow_forwardQuestion 2 Quality (x) is the ratio of the mass of liquid to the total mass of the vapor in the mixutre.

O The ideal degrees of superheat of steam passing through throttling calorimeter is 5.5°C O Typical condition of steam entering a calorimeter is wet-vapor mixture and superheated when exiting O Electrical calorimeter operates approximately as barrel calorimeter with modifications in some parts. O If a throttling calorimeter is insufficient, there is a need to measure the pressure and temperature of steam passing through it. O For a separating calorimeter. series of obstacles are found within the separating charmber which separate liquid particles from vapor. O Actual quality of the steam is equal to the computed value of dryness fraction, neglecting lossies O For separating and throttling calorimeter, the quality 2 is greater or higher than quality 1.arrow_forwardWhen performing a combustion efficiency test, digital flue gas will measure what four parameters?____________, and________.arrow_forward
