A hotel had 1360 bookings for accommodation in a month. Of these 940 were for one night. Business bookings amounted to 813 of the total number, all but 141 being for one night. Leisure bookings amounted to a further 362, the remaining bookings being associated with functions (weddings etc.). Only 23 of these latter bookings were for more than one night.
Draw up a two-way table for these figures with rows for the types of booking and columns for the length of stay. Deduce the figures that are not given by using the information provided
Using T flip-flops, show the block diagram for a 3-bit ripple counter and its input and output waveforms.
A balanced delta-connected load with a per-phase impedance of 30 + j10 Ω is connected in parallel with a balanced wye-connected load with a per phase impedance of 40-j10 Ω.
A closed tank, 1 m3 in volume is filled with water at 1 bar 80 °C. A second identical tank contains 20 kg of steam at 20 bar. What is the mass of water in tank 1?
Develop a two-dimensional addressing system using a 6-to-64 decoder, a 64-word×128- bit matrix, and 16-input multiplexers. How many gates would such a system require?
Assuming that no lead was originally present, that all the 206Pb formed over the years has remained in the rock, and that the number of nuclides in intermediate stages of decay between 238U and 206Pb is negligible, calculate the age of the rock. (..
Figure shows a simple heat-exchange system. A feed stream is heated by heat exchange in a plate exchanger and then further heated in a steam heater before entering a fixed-bed reactor. The product from the reactor is cooled in the plate exchanger ..
Find the relationship between voltage across the membrane and the concentration of CaCl2 before equilibrium is reached.
An eight-liter pressure cooker contains a mixture of steam and liquid water at 2 bar. Through a level indicator we can see that the liquid occupies 25% of the volume inside the cooker.
Assume that an As i mplant leads to a uniform electron concentration of 1019 cm·3 down to a depth of 0.1 µm and a mobility of 100 cm2 .V1 .s·1 . Determ ine the resistivity and the sheet resisti vity of the implanted layer.
Calculate the ?S for the transfer of one mole of octane to water using the change in multiplicities assumed for the first shell of water molecules surrounding the molecules.
Obtain the step response of the closed-loop system to verify the stability of the closed-loop system with actuator saturation.
A three-phase, wye-connected, cylindrical-rotor, synchronous motor, with negligible armature resistance and a synchronous reactance of 1.27 Ω per phase, is connected in parallel with a three phase, wye-connected load taking 50 A at 0.707 lagging p..
