- A 0.15 kg/s stream of water flows through a 5 cm diameter tube at an inlet Hint: Engineering"To solve this problem, we can use the concept of convective heat transfer. The rate of heat transfer from the water to the air can be calculated using Newton's law of cooling:Q = h A Δ TWh..
- A 0.9 m square shallow foundation is supported by dense sand Hint: Engineering"Relative density or the specific gravity, is mainly the ratio of the density or the mass of a unit volume, of a substance to the density of that given reference material.can be calculated ..
- A 1-ph transformer operates from a 230-V supply Hint: Engineering"The secondary terminal voltage can be calculated by using the following formula:V2 = V1 * (N2 / N1) * (R2 / (R2 + Rl2 + Rm2))Where:V1 = 230 V (Primary voltage)N2 / N1 = 4 (Turns ratio)R2 =..
- A 100 W lightbulb generates 95 W of heat, which is dissipated through a glass Hint: Engineering Pressure is how much power applied opposite to the outer layer of an article for every unit region. The image for it is "p" or P.Types of Pressure - Outright Strain, Check Tension, Di..
- A 15-L mixture of acetone/isopropanol is to be separated by batch distillation Hint: EngineeringIsopropanol, or isopropyl alcohol, is a clear, colorless liquid that emits an odor that resembles acetone. It is a commercially available product mainly is found as a 70% solution in rubbin..
- A 150-mm ID potable water distribution pipe has water flowing at a velocity Hint: EngineeringPast efforts to denote the Gilliland correlation by an analytic expression were not reasonable. It was essential to divide the span into two or three units with a distinct equation for each..
- A 15k load is applied at node 2 in the x-direction Hint: Engineering The principal axes of latency of an inflexible body are a bunch of tomahawks going through the article's focal point of mass and connect with the item's mass conveyance to such an ext..
- A 250 KVA single phase transformer has iron loss of 1.8KW Hint: Engineering"Since the the input power at rated load is 250 kwa. If the losses are 1.8Kw and 2000w, then the total loss is 2800w. Then calculate the output power in the load. Then the efficie..
- A 3 ϕ cylindrical-rotor synchronous machine (SM) and a separately Hint: EngineeringTo transfer the power from the DC source to the AC source, the DCM needs to act as a motor. And, the SM acts as the generator. Therefore, to transfer power from the AC source to the DC sour..
- A 35% solution of potassium dichromate is fed to a crystallizer-dryer system Hint: EngineeringA recycling stream is one in which a portion of a process unit's outlet is blended with fresh feed and then delivered back into the unit. There are many reasons to use a recycle stream, inc..
- A 4 meter long steel member is set snugly between two walls and then heated so that the temperature rise Hint: EngineeringCompressive stress is a force that triggers a material to deform and take up a smaller volume that it was originally. High compressive stress leads to failure due to tension. It is calculat..
- A 4-pole, lap connected D.C. machine has 540 armature conductors Hint: Engineering"The e.m.f. generated in the DC machine can be calculated by:E = ( P Φ Z N ) / 60A,in which,P is the number of poles, Φ is the flux per pole, Z is the total number of armature con..
- A 50 cm long, 800 W electric resistance heating element with diameter Hint: Engineering In a heating process, the stage change from a strong into a fluid happens when the material arrives at a material-explicit stage change temperature. In the burning of fuel, carbon, an..
- A 50-mm-diameter and 150-mm-long undisturbed soil sample was collected Hint: Engineeringii)The volume of voids to the volume of solids in a combination is measured as the void ratio. In the field of materials science, it is a dimensionless quantity that is closely associated w..
- A 60 cm diameter, impeller centrifugal pump has the following characteristic at 750 rev min−1 Hint: EngineeringDiameter is any line segment through the middle of the circle, the endpoints of which lie on the circle. It can also be defined as the circle's longest chord. The length of a diameter is al..
