Q: The water equivalent of a 0.7 kg brass calorimeter is: 0.064 kg Malleable cast
iron is produced by: Giving white cast iron castings a long heat treatment at
about 925°C, followed by slow cooling If Young's Modulus and the stress that a
body is subjected to is known, which of the following can be calculated?
Answer:
Amount of strain produced The boiling point of water on the Kelvin scale is: 373 The
material balance table provides the: Pressure, temperature, composition and flow
rates of the various process streams An airplane travels 1000 km eastwards for 2
hours. Its average speed in m/s is: 138.89 m/s
,Q: Compounds that are classified as acids have which of the following
characteristics?
Answer:
1. They have a soapy feeling 2. They have a sour taste 3. They change blue litmus
paper red 4. They will conduct electricity 2, 3, 4 The power required to drive a pump
which has an output of 15 kW and an efficiency of 90% is: 16.67 kW Oxygen is
lanced into the molten metal in the Electric Arc Furnace to: 1. Increase the heat and
promote faster melting of the pig iron 2. Form oxides that float to the surface 3.
Lower the carbon content to the desired levels 4. Enhance the electrical current flow
2, 3 Each circular half of the figure-8 race track shown here has an outside radius of
145 m. Calculate the minimum size, in hectares, of the rectangular lot that can
contain this race track. A flywheel changes speed uniformly from 400 rpm to 100
rpm in 1 minute. What is the angular retardation of the flywheel in rad/s²? 0.523
rad/s² In chemistry, bases are also called: Alkalines Work done in a cylinder at
constant pressure can be defined using the formulas: 1. Work Done (J) = Pressure
(kPa) x Area (m²)
, Q: 2. Work Done (J) = Pressure (kPa) x Area (m²) x Distance (m) 3. Work Done (J)
= Force (N) x Area (m²) 4. Work Done (J) = Force (N) x Distance (m) the force
moves 2, 4 A sliding face of a slide valve of a steam engine is 150 mm by 300
mm, and the steam pressure on the back of the valve is 1200 kN/m². If the
coefficient of friction is 0.02, what is the force required to move the valve?
Answer:
1080 N The unit of relative density is: None How many kJ of heat is required to
produce 32 kg of steam 88% dry at 3000 kPa from feedwater at 90°C? 70774.9 kJ
The information boxes at the bottom of a Construction Drawing give exact details
about: 1. Parts of the equipment 2. Operating parameters 3. Connections to the
equipment 4. Direction of flow of the fluids through the equipment 5. The
composition of the fluids flowing through the equipment 6. Auxiliary piping
requirements 1, 3, 6 Aqueous solutions of acids have the following characteristics: 1.
They have a value between 0 - 7 on the pH scale 2. They have a value between 7 - 14
on the pH scale 3. They change the color of litmus paper from red to blue 4. They
change the color of litmus paper from blue to red 5. They have the ability to
neutralize bases 1, 4, 5
