Design a database to produce the following reports. do not use any surrogate keys in your design. for each guide, list the guide number, guide last name, guide first name, address, city, state, postal code, telephone number, and date hired. for each trip, list the trip id number, the trip name, the location from which the trip starts, the state in which the trip originates, the trip distance, the maximum group size, the type of trip (hiking, biking, or paddling), the season in which the trip occurs, and the guide number, first name, and last name of each guide. a guide may lead many trips and a trip may be led by many different guides. for each client, list the client number, client last name, client first name, address, city, state, postal code, and telephone number

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.

For the closed feedwater heater below, feedwater enters state 3 at a pressure of 2000 psia and temperature of 420 °f at a rate of ix10 ibhr. the feedwat extracted steam enters state 1 at a pressure of 1000 psia and enthalpy of 1500 btu/lbm. the extracted er leaves at an enthalpy of 528.7 btu/lbm steam leaves as a saturated liquid. (16) a) determine the mass flow rate of the extraction steam used to heat the feedwater (10) b) determine the terminal temperature difference of the closed feedwater heater
