To avoid cavitation in a pump, one of the few items that a designer has control over is the     

According to Palmer, which ethical view challenges the anthropocentric nature of Western ethics?

Multiply using the product rule.

Identify the given number as “Rational”, “Irrational”, or “Not a real number”. If the number is rational, give its exact value. If the number is irrational, give a decimal approximation to the nearest thousandth.

Use the quadratic formula to solve the equation.9×2 + 5x + 1 = 0

A 0.5 kg block of aluminum (specific heat capacity = 900 J/kg·°C) is heated from 20°C to 80°C using a 2.0 kg container of water (specific heat capacity = 4186 J/kg·°C) initially at 25°C. Assume no heat is lost to the environment. Calculate the heat energy required to raise the temperature of the aluminum block from 20°C to 80°C.

Draw a typical pump characteristic curve and label the axes with units (British). Then draw a typical system head curve on the same graph. Clearly label both curves and the match point.

Use the quadratic formula to solve the equation. (All solutions are real numbers.)4×2 – 3x – 7 = 0

A heat pump is used to heat a home during the winter. The heat pump extracts heat from the outside air at a temperature of -5 degrees Celsius and delivers it to the inside air at 20 degrees Celsius. The heat pump operates with a coefficient of performance (COP) of 3.5. If the heat pump consumes 2.5 kW of electrical power, calculate the total heat energy delivered to the home per second. (In kW)
