You have the opportunity to offer fire insurance to your friends and neighbors. For every policy you take, you incur the following probabilistic annual risk: Annual Loss Probability of Loss $0 60% $500 10% $5,000 10% $20,000 15% $100,000 5% If you incur a loss, you pay it at the end of the year. How much should you charge each policy holder a month, collected at the beginning of each month and held in an account earning a nominal, annual, 6%, to make an annual profit of $1,000 per policy holder?

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.

The drive force for diffusion is 7 fick's first law can be used to solve the non-steady state diffusion. a)-true b)-false

Air is compressed isentropically from an initial state of 300 k and 101 kpa to a final temperature of 1000 k. determine the final pressure using the following approaches: (a) approximate analysis (using properties at the average temperature) (b) exact analysis
