When is the output of an OR-gate LOW?
Answer:
The OR gate is a digital logic gate that implements logical disjunction (∨) from mathematical logic – it behaves according to the truth table above. A HIGH output (1) results if one or both the inputs to the gate are HIGH (1). If neither input is high, a LOW output (0) results.
Give the largest positive number that can be represented in 13 bits for the two cases:
a) Unsigned number, and b) Signed number
Show the binary, decimal, and hexadecimal representations of the number for each case
The largest positive number that can be represented in 13 bits for the two cases are
A) Unsigned number
The largest unsigned no can be represented with 13bits as[tex](2)^n - 1 = (2)^{13} - 1 = 8191[/tex]
In Binary - [tex](1111111111111)_2[/tex]
In decimal - [tex](8191)_{10}[/tex]
In hexadecimal - [tex](1FFF)_{16[/tex]
B) Signed number
The largest signed no can be represented with 13bit as[tex]2^n = 2^{13} = 8192[/tex]
The range is from [tex](2^n-1)[/tex]
therefore, the maximum value is [tex](4096)_{10}[/tex]
In binary - [tex](1000000000000)_2[/tex]

Explanation:
A student borrows $60,000 for business school at 6.5% stated annual interest with equal monthly payments over 10 years. Consider this as a loan with no payments or interest during school so that the problem structure is equivalent to a standard loan received one period before the first payment. How much is the monthly payment?
Answer:
$681.29
Explanation:
The amortization formula seems to apply. The monthly payment on a loan of P at rate r for t years is ...
A = P(r/10)/(1 -(1 +r/12)^(-12t))
For the given loan parameters, the monthly payment is ...
A = $60,000(0.065/12)/(1 -(1 +0.065/12)^(-12·10)) ≈ $681.29
The monthly payment is $681.29.

A pump of a water distribution system at 25°C is powered by a 15 kW electric motor whose efficiency is 90 percent. The water flow rate through the pump is 50 L/s. The diameters of the inlet and outlet pipes are both 5 cm and the elevation difference across the pump is negligible. If the absolute pressures at the inlet and outlet of the pump are measured as 100 kPa and 300 kPa, respectively, determine the friction loss in the system.
The friction loss in the system is 3.480 kilowatts.
Procedure - Friction loss through a pumpPump modelLet suppose that the pump within a distribution system is an open system at steady state, whose mass and energy balances are shown below:
Mass balance[tex]\dot m_{in}-\dot m_{out} = 0[/tex] (1)
[tex]\dot m_{in} = \frac{\dot V_{in}}{\nu_{in}}[/tex] (2)
[tex]\dot m_{out} = \frac{\dot V_{out}}{\nu_{out}}[/tex] (3)
Energy balance
[tex]\eta \cdot \dot W_{el} + \dot m_{in}\cdot (h_{in}-h_{out}) - \dot W_{f} = 0[/tex] (4)
Where:
[tex]\dot m_{in}[/tex] - Inlet mass flow, in kilograms per second.[tex]\dot m_{out}[/tex] - Outlet mass flow, in kilograms per second. [tex]\dot V_{in}[/tex] - Inlet volume flow, in cubic meters per second. [tex]\dot V_{out}[/tex] - Outlet volume flow, in cubic meters per second. [tex]\nu_{in}[/tex] - Inlet specific volume, in cubic meters per kilogram.[tex]\nu_{out}[/tex] - Outlet specific volume, in cubic meters per kilogram.[tex]\eta[/tex] - Pump efficiency, no unit.[tex]\dot W_{el}[/tex] - Electric motor power, in kilowatts.[tex]h_{in}[/tex] - Inlet specific enthalpy, in kilojoules per kilogram.[tex]h_{out}[/tex] - Outlet specific enthalpy, in kilojoules per kilogram. [tex]\dot W[/tex] - Work losses due to friction, in kilowatts. Data from steam tablesFrom steam tables we get the following water properties at inlet and outlet:
Inlet
[tex]p = 100\,kPa[/tex], [tex]T = 25\,^{\circ}C[/tex], [tex]\nu = 0.001003\,\frac{kJ}{kg}[/tex], [tex]h = 104.927\,\frac{kJ}{kg}[/tex], Subcooled liquid
Outlet
[tex]p = 300\,kPa[/tex], [tex]T = 25\,^{\circ}C[/tex], [tex]\nu = 0.001003\,\frac{kJ}{kg}[/tex], [tex]h = 105.128\,\frac{kJ}{kg}[/tex], Subcooled liquid
Calculation of the friction loss in the systemIf we know that [tex]\dot V_{in} = 0.05\,\frac{m^{3}}{s}[/tex], [tex]\nu_{in} = 0.001003\,\frac{m^{3}}{kg}[/tex], [tex]h_{in} = 104.927\,\frac{kJ}{kg}[/tex], [tex]h_{out} = 105.128\,\frac{kJ}{kg}[/tex], [tex]\eta = 0.90[/tex] and [tex]\dot W_{el} = 15\,kW[/tex], then the friction loss in the system is:
[tex]\dot W_{f} = \frac{\dot V_{in}}{\nu_{in}}\cdot (h_{in} - h_{out}) + \eta \cdot \dot W_{el}[/tex]
[tex]\dot W_{f} = \left(\frac{0.05\,\frac{m^{3}}{s} }{0.001003\,\frac{m^{3}}{kg} } \right)\cdot \left(104.927\,\frac{kJ}{kg}-105.128\,\frac{kJ}{kg}\right) + (0.90)\cdot (15\,kW)[/tex]
[tex]\dot W_{f} = 3.480\,kW[/tex]
The friction loss in the system is 3.480 kilowatts. [tex]\blacksquare[/tex]

When is the output of a NAND-gate HIGH?
Answer:
In digital electronics, a NAND gate (NOT-AND) is a logic gate which produces an output which is false only if all its inputs are true; thus its output is complement to that of an AND gate. A LOW (0) output results only if all the inputs to the gate are HIGH (1); if any input is LOW (0), a HIGH (1) output results.

where t is time in seconds
a,calculate the expression for V(in^3) in terms of t(minute)
b,
The expression of V(m³)=e^(t(s)) to make V in in³ and t in minutes is;
V(in³) = (¹/₆₁₀₂₄)a[tex]e^{\frac{1}{60}bt(h)[/tex]
We are given that;
Volume of microbial culture is observed to increase according to the formula;
V = e^(t)
where;
t is in seconds
V is in m³
We want to now express V in in³ and t in minutes.
Now, from conversions;
1 m³ = 61024 in³
Also; 1 second = 1/60 minutes
according to formula for exponential decay, we know that;
V = ae^(bt)
Thus, we have;
61024V = ae^(¹/₆₀b(t(h))
