A gas turbine plant receives air at 1 bar and 290°K and compresses it to 5 bar. If the temperature of air after compression is 1000°K; find the thermal efficiency of the turbine
A company is planning to provide an extra discount to its customers. every order has an order I'd associated with it which is a sequence of digits.the discount is calculated as the count of the unique repeating digits in the order I'd.
What is the capacitance of a parallel plate capacitor with metal plates, each of area of 6.00 m2, separated by 10.00 mm?
A company is offering a special discount to its customers based on an algorithm. Two range values are fed to the algorithm and in return t will calculate the discount to offer to the customers. The discount is calculated as the sum of all the prime numbers within the defined range including the range values if the range values are the prime numbers
Write an algorithm to find the special discount given to the customers
