A boiler uses 18 kg air per kg of fuel. Determine the minimum height of
chimney required to produce a draught of 25 mm of water. The mean
temperature of chimney gases is 335° C and that of outside air 22° C.
Write a program to overload operators in the same program by writing suitable operator member functions for following expression: O7= ((O1 % O2)>(O3 || O4) - (O5>O6)) [Here O1,O2,O3,O4,O5,O6 and O7 are objects of a class “overloading”, and this class is having one integer data member]
Write a program to take input for n number of doctor records and write records of all cardiologists in a file named: “record1”. Also write records of all those doctors in another file named: “record2” who are taking salary more than INR 80,000. After writing records in both files, merge their contents in another file: “finalrecord” and read all records of “finalrecord” file and display on screen. [Attributes of doctor: doc_id, doc_name, doc_specialization, doc_salary]
Consider the reaction: 2C2H2(g) + 3O2(g) → 4CO2(g) + 2H2O(l);
ΔHfº C2H2(g) = 54.20 kJ/mol
ΔHfº H2O(l) = –68.30 kJ/mol
ΔHfº CO2(g) = –94.10 kJ/mol
