The objective of this lab is to design a digital clock using a DS1307 external clock chip. The first step is to interface the clock chip to the microcontroller using an I2 C network. The second step is to design low-level drivers to allow the microcontroller to send and receive data from the DS1307. The next software layer includes functions such as Set Time, Format Time, and Read Time. The highest level is a main program that implements a digital clock using an LED or LCD display. Two, three, or four momentary switches will be used to control the operation of the digital clock.
a tank has two rooms separated by a membrane. room a has 1 kg air and volume 0.5 m3 room b has 0.75 m3 air with density
a car is driven east for a distance of 43 km then north for 23 km and then in a direction 29deg east of north for 27
A cylinder with a piston restrained by a linear spring contains 2kg of carbon dioxide at 500 kPa, 400 C the system is now cooled to 40C, at which point the pressure is 300 kPa. You may assume ideal gas behavior with constant specific heat value Cv=0...
Determine the maximum theoretical rate of heating provided by a heat pump, in kW per kW of power input, in each of two cases: The role of the cold reservoir is played by (a) the atmosphere at 2208C, (b) ocean water at 58C.
Determine the coefficients for the balanced chemical reaction at stoichiometric conditions for both petrol and E10 with air.
A spherical shell of inner and outer radii ri and ro, respectively, is filled with a heat-generating material that provides for a uniform volumetric generation rate (W/m3) of q. The outer surface of the shell is exposed to a fluid having a temperatur..
Find the velocity of the bullet and block just after impact.
The force on a weir is to be predicted by studying the ?ow of water over a 1:10 scale model. If 1.8 m3=s is expected over the weir, what ?ow rate should be used in the model study? What force should be expected on the weir if 20 N is measured on t..
two rigid tanks are connected by a valve. tank a contains 0.2 m3 of water at 400 kpa and 80 percent quality. tank b
a 20-m3 tank contains nitrogen at 23degc and 600 kpa. some nitrogen is allowed to escape until the pressure in the tank
calculate an estimate of x(0.25) accurate to three decimal places.
For T 5 808F, determine the steam quality at the turbine exit, the steam mass flow rate, in lb/h, and the thermal efficiency. Plot the quantities of part (a) versus T ranging from 80 to 1058F.
