The manager has estimated that monthly demand for recorders is normally distributed, with a mean of 180 recorders and a standard deviation of 60. Determine the number of recorders the manager should order each month to meet 90% of customer demand.
A small pump is driven by a 2 kW motor with liquid water at 150 kPa, 10°C entering. Find the maximum water flow rate you can get with an exit pressure of 1 MPa and negligible kinetic energies.
What is meant by toughness? How does it differ from strength? Why is there a transition from ductile to brittle behavior at a transition crack length, ccrit?
A charge of +q is located at the origin, while an identical charge is located on the x axis at x = 0.46 m. A third charge of +3q is located on the x axis at such a place that the net electrostatic force on the charge at the origin doubles, its dir
You drive on the highway with 120 km/h on a day with 17°C, 100 kPa atmosphere. When you put your hand out of the window flat against the wind you feel the force from the air stagnating, i.e. it comes to relative zero velocity on your skin.
Calculate the air temperature and pressure at the stagnation point right in front of a meteorite entering the atmosphere (-50 °C, 50 kPa) with a velocity of 2000 m/s. Do this assuming air is incompressible at the given state.
Calculate the Gibbs free energy change of a rubber band stretched to 5 times its original length with concurrent contractions in its other two dimensions of 2.24 times at 25 C.
Imagine dropping a soccer ball. The first bounce will be the highest, eand each bounce after that will be lower until the ball stops bouncing. Describe the energy changes that take place and explain how energy is conserved.
A heat pump has a coefficient of performance that is 50% of the theoretical maximum. It maintains a house at 20°C, which leaks energy of 0.6 kW per degree temperature difference to the ambient.
