You are designing a new thermometer using Galinstan, an alloy of gallium, indium, and tin that is a liquid at normal living temperatures. The coefficcient of thermal expansion is 190*10^-6 (1/kelvin). The thermometer will contain four cubic centimeters of Galinstan, most of which is in the bulb or reservoir that is connected to a capillary tube up which the liquid moves as it expands. If your design specifications are to have a 2millimeter change in the position of the liquid in the capillary tube for each degree Fahrenheit change in temperature, what is the diameter of the capillary tube, assuming it has a circular cross section?
How many watts of power would it take to heat 1 L of water(weighing 1.0 kg) by 10 degrees Celsius n 1.0 h Assume no heat losses occur, so all of the energy expneded goes into heating the water.

A surveyor is going to take a 5.5 mile sight across a lake from the top of one tower to a target on the top of another tower. It is desired to keep the line of sight 6 ft above the lake surface.
A pump has the following pump curve is pumping at a rate of 5000gpm. Calculate (a) the total head the pump is pumping against. (b) brake horsepower required to drive the pump.
If the Greenshields model describes the relationship between speed and density on the highway, the jam density of the highway is 112 veh/mi, and the mean free speed is 64.5 mph,
If a W14x53 is 20 ft long (simply supported) and is loadeduniformly to its moment capacity what is the maximumdeflection? What will be the uniform load so to get the maximum deflection?
Part B (Assignment): by trial and error, find the angle that will give the minimum force F to make a basket (hint: try 52 degrees)The trajectory of the ball will make a basket when x = L and y = Hb
The perpendicular distance between two parallel tangents of a reversed curve is 20m. The azimuth of the back tangents of the curve is 270 00 and the azimuth of the common tangent is 310.
Water is to be boiledat sea level in a 30 cm diameter stainless steel pan on top of a3-kW electric burner. If60% of the heat generated by the burner is transferred to thewater during boiling, determinethe rate of evaporation of water.
This project is expected to have a first cost of $2,000,000 and an annual maintenance cost of $50,000. In addition, major repairs costing $250,000 will be required after 25 years and each 15 years thereafter.
The acrylic plastic rod is 200mm long and 15mm in diameter. If an axial load of 300N is applied to it, determine the change in its length and the change in its diameter. Ep = 2.70 GPa, Vp = 0.4.
Water flows through a 75 mm constriction in a horizontal 150 mm pipe. If the pressure in the 150 mm section is 345 kPa and that in the constriction 207 kPa, calculate the velocity in the constriction and the flowrate.
