(1) build the itemtopurchase class with the following specifications: attributes item_name (string) item_price (float) item_quantity (int) default constructor initializes item's name = "none", item's price = 0, item's quantity = 0 method print_item_cost() (2) in the main section of your code, prompt the user for two items and create two objects of the itemtopurchase class. (3) add the costs of the two items together and output the total cost.

Apump is used to circulate hot water in a home heating system. water enters the well-insulated pump operating at steady state at a rate of 0.42 gal/min. the inlet pressure and temperature are 14.7 lbf/in.2, and 180°f, respectively; at the exit the pressure is 60 lbf/in.2 the pump requires 1/15 hp of power input. water can be modeled as an incompressible substance with constant density of 60.58 lb/ft3 and constant specific heat of 1 btu/lb or. neglecting kinetic and potential energy effects, determine the temperature change, in °r, as the water flows through the pump.
