Q1. A steel slab manufacturing plant melts 750 tons of steel for the continuous casting operation every day. How much energy is consumed during each production day? Sate your answer in GJ (5) Energy consumed = mass x specific heat capacity x change in temperature Q2. High density polyethylene material is used in petrol station installations as pipe. If a 16 m long pipe is exposed to high temperatures of 100 °C, what will be the change in length? (6) Change in length is equal to the original length x coefficient of linear expansion x change in temperature. Q3. During the casting process, a low density grey cast iron material measuring 1 cubic metre has to be heated. How much heat energy will be required to raise the temperature of the material from room temperature to the melting point. If the operation is to take place in 6 hours duration, how much power is required? Q=mxcXAT (10)
