why in digital system most of the gates in logic Zero current pass more increace ? explain it.

Classify the following flows as laminar or turbulent a) Water at 200C flowing in a 0.30m diameter pipe at 1.1m/s. b) Oil of specific gravity 1.1, viscosity 0.05kg/m.s at 200C flowing in a 0.15m diameter pipe at 0.5m/s

The outputs of four registers, A, B, C, D, H, L are connected through 8:1 line
multiplexer to the input of a fifth register, X. Each register is 16 bits long. The
required transfers are dictated by four timing variables, T0 through T3 as follows:
T0 : X←A
T1 : X←B
T2 : X←C

The first-year maintenance cost for a new car is estimated to be $150, and it increases at a uniform rate
of 15%per year. Using an 8%interest rate, calculate the present worth (PW) of the cost of the first 5
years of maintenance.

Gerard has purchased a new car. He wishes to set aside enough money in a bank account to pay the
maintenance for the first 5 years. It has been estimated that the maintenance cost of a car is as follows:
Year Maintenance Cost
1 $100
2 120
3 140
4 160
5 180
Assume the maintenance costs occur at the end of each year and that the bank pays 5% interest.
How much should Gerard deposit in the bank now?

The Highway Department expects the cost of maintenance for a piece of heavy construction equipment
to be $5000 in year 1, to be $5500 in year 2, and to increase annually by $500 through year 10. At an
interest rate of 10% per year, determine the present worth of 10 years of maintenance costs.

A debt of P25,000 with interest at the rate of 8% compounded monthly is to be amortized by 5 equal
payments at the end of each month, the first payment is to be made after 1 year. Find the monthly
payment and construct an amortization schedule.
